Modernize your cloud. Maximize business impact.
For small and mid-sized businesses (SMBs), cloud migration is an opportunity to modernize operations. However, it can also expose security blind spots if not planned carefully. Misconfigured access, exposed data, or missing compliance controls can turn a technical win into a reputational risk.
Take the case of a mid-sized healthcare provider migrating patient records to Amazon S3. The migration itself goes well, but they might overlook S3 Block Public Access by default. A week later, a routine security scan reveals that some storage buckets are publicly accessible. This puts the company at risk of violating HIPAA rules. It’s caught in time, but the instance triggers a full audit and weeks of remediation.
Incidents like this usually happen because the migration overlooks essential safeguards. This article breaks down the most common security pitfalls SMBs face during cloud migration, and shows how to avoid them with practical, preventive steps.
Key takeaways:
- Treat security as a migration stream: Security should be integrated from the planning phase through execution, not bolted on after workloads move.
- Don’t carry over legacy risks: Lift-and-shift approaches often transfer outdated controls. Always reassess configurations and patch known vulnerabilities before migration.
- IAM missteps cause the most damage: Overly permissive roles or missing MFA setups remain leading causes of breaches. Tighten access controls early.
- Compliance doesn’t auto-transfer: Moving to the cloud doesn’t automatically preserve HIPAA, PCI, or GDPR compliance. Logging, data handling, and access reviews must be revalidated.
- Small teams can win with the right tools: Cloud-native security services and automation help SMBs build strong defenses, especially when paired with expert guidance.
Key cloud migration security challenges for SMBs, and how to solve them?
Cloud migration introduces a shift in how IT environments are secured. For SMBs, this shift often happens under resource constraints, without specialized security teams or mature DevSecOps practices in place. As a result, critical vulnerabilities frequently emerge.
According to IBM’s cost of a data breach report, 40% of data breaches involved data stored across multiple environments. Breached data stored in public clouds incurred the highest average breach cost at USD 5.17 million.
Common issues like open Amazon S3 buckets, broad IAM access, insecure APIs, and unpatched workloads often stem from rushed migrations. SMBs can reduce risk by treating security as a parallel track, encrypting data, enforcing least-privilege access, automating compliance, and baking security into CI/CD pipelines.
SMBs will face many security challenges during transition, but each of them has a fix that can be implemented early to reduce cost and downtime:
Challenge 1: Data exposure during transfer or storage
When moving data to the cloud, it’s easy to assume AWS will handle encryption by default. But during migration, especially when using tools like AWS DMS or moving large datasets to Amazon S3, data can pass through unsecured channels or land in buckets without encryption turned on. That’s when it gets risky. A misstep here could expose sensitive info like customer records, financials, or health data.
The fix: To keep data protected, encryption needs to be covered in two places: when it's moving and when it’s sitting in AWS.
For data in transit, enforce TLS 1.2 or higher.
- When using AWS DMS, turn on SSL for every connection point.
- Set bucket policies in Amazon S3 to reject unencrypted uploads.
For data at rest, turn on encryption by default.
- Use AWS KMS (Key Management Service), either AWS-managed or customer-managed keys.
- Enable encryption on Amazon S3, RDS, and EBS volumes from the start.
- Use AWS Config to alert if anything’s left unencrypted.
- Keep an eye on key usage and access patterns with AWS CloudTrail.
How one SMB handled it: A growing dental clinic group migrating its patient database to Amazon RDS ran into a pitfall. Backups weren’t encrypted, and neither were the Amazon S3 uploads coming from old file exports. However, with the help of their AWS partner, they enabled SSL connections to the Amazon RDS instance, switched on encryption using a customer-managed KMS key, and applied Amazon S3 policies to block any unencrypted objects. They also routed DMS traffic through a VPN tunnel using IPSec with AES-256.
The migration wrapped without a hitch, and passed a HIPAA audit two months later.
Challenge 2: Weak or overly permissive IAM policies
Many SMBs start out with all-hands admin access just to “get things working” during early cloud stages. But that kind of shortcut doesn’t scale. Broad IAM roles, like giving full AdministratorAccess to multiple users or using wildcard permissions (*), leave the door wide open for accidents or attacks. A single compromised user account could mean access to everything from Amazon S3 buckets to billing dashboards.
The fix: Secure IAM starts with discipline, not complexity. AWS gives the tools. SMBs just need a plan.
- Least privilege first: Define roles around job functions. For example, DevOps engineers might get full access to Amazon EC2 and AWS CloudFormation, but only read access to Amazon S3.
- Use IAM policies with explicit, scoped permissions instead of wildcards.
- Enforce MFA (Multi-Factor Authentication) for all users, especially those with console access.
- Centralize identity using AWS IAM Identity Center (formerly AWS SSO), and connect it to the existing directory (like Microsoft AD or Okta).
- Set up regular reviews using IAM Access Analyzer to catch unused permissions or over-provisioned roles.
How one SMB handled it: A fintech startup had six developers sharing a root account during testing. Fast, but dangerous. On the suggestion of their AWS partner, they split out individual IAM roles, restricted access based on team functions, and required MFA for each user. They implemented IAM Identity Center and linked it with Google Workspace for strong login control. Within a week, they went from full-access chaos to tight, auditable roles that passed their first investor security review.
Challenge 3: Misconfigured cloud environments
Default settings in AWS are designed for flexibility, not security. That’s fine when spinning up test environments, but it’s risky in production. It is easy to overlook things like open Amazon S3 buckets, 0.0.0.0/0 rules in security groups, or disabled encryption on Amazon RDS or EBS volumes. These misconfigurations leave systems exposed to the internet or unencrypted by default.
The fix: Security misconfigurations are preventable with the right guardrails in place.
- Use AWS Config to continuously scan for misaligned settings across services (e.g., unencrypted volumes, non-compliant IAM roles).
- Enable AWS Security Hub to consolidate security alerts and automatically check the environment against AWS best practices.
- Trusted Advisor provides real-time recommendations across security, performance, and cost, flagging things like publicly accessible storage or overly broad access rules.
- Establish service control policies (SCPs) in AWS Organizations to prevent high-risk configurations before they happen.
- Automate remediation with tools like AWS Systems Manager Automation or integrations with third-party platforms like Palo Alto Prisma Cloud or Datadog.
How one SMB solved it: A healthcare tech company found that one of its Amazon S3 buckets used for diagnostic image uploads was accidentally made public during testing. However, with guidance from their AWS partner, they activated Security Hub and AWS Config, which flagged the exposure. They locked down the bucket, enforced encryption at rest, and added guardrails to prevent similar issues in future environments. That quick action helped them avoid a serious HIPAA compliance violation.
Challenge 4: Unsecured APIs and integration points
During migration, existing APIs used for mobile apps, third-party integrations, or internal tools are often reused without being reassessed for cloud exposure. What was once protected behind a corporate firewall might now be reachable over the public internet. Without safeguards like authentication, rate limiting, or request validation, these endpoints become easy targets for abuse, injection attacks, or data exfiltration.
The fix: AWS offers purpose-built tools to lock down APIs without complicating development:
- Use Amazon API Gateway to serve APIs through a managed layer that supports throttling, access control, and monitoring out of the box.
- Protect public endpoints with AWS WAF (Web Application Firewall) to block common attack patterns like SQL injection or cross-site scripting.
- Enforce authentication and authorization using Amazon Cognito, custom tokens, or IAM roles for internal services.
- Log and monitor API activity with CloudWatch Logs and AWS X-Ray to detect anomalies in usage or performance.
- Use resource policies and VPC links to limit API access to only trusted networks when needed.
How one SMB solved it: A fintech startup that migrated its customer dashboard to AWS was exposing internal APIs for billing and account updates without authentication. After noticing unusual traffic patterns, their AWS partner helped deploy API Gateway in front of the services, integrated AWS WAF to filter malicious traffic, and implemented OAuth2 authentication through Cognito. These changes shut down the vulnerability and gave the team better visibility into API usage going forward.
Challenge 5: Rehosting without revisiting security posture
Many SMBs choose a lift-and-shift approach for speed, migrating workloads “as-is” to the cloud. But this often means legacy vulnerabilities make the jump too. These can include hardcoded credentials in config files, outdated OS versions, unpatched libraries, or services running with admin-level access. Once in the cloud, these overlooked issues become more dangerous due to increased exposure and scale.
The fix:
A successful rehost still needs a security checkpoint before workloads go live in AWS:
- Run pre-migration assessments to flag risky dependencies or OS-level vulnerabilities.
- Use AWS Systems Manager Patch Manager to automate patching for Amazon EC2 instances across both Linux and Windows.
- Store and rotate credentials securely using AWS Secrets Manager instead of hardcoding them in applications.
- Use Amazon Inspector to scan for known CVEs and misconfigurations as soon as the workload is in AWS.
- Apply IAM roles instead of access keys to give services temporary, scoped permissions.
How one SMB handled it: A regional HR software company rehosted its on-prem application servers to Amazon EC2 with minimal changes. Post-migration, they found hardcoded database credentials in application configs and several unpatched packages. With guidance from their AWS partner, they used AWS Inspector to identify vulnerable packages, automated OS patching via AWS Systems Manager, and moved credentials to AWS Secrets Manager. This not only improved their security posture but also passed a third-party audit required for a new enterprise client.
Challenge 6: Gaps in compliance visibility
When SMBs migrate workloads to the cloud, especially in regulated industries like healthcare or finance, compliance requirements can slip through the cracks. Teams often lose visibility into how HIPAA, PCI-DSS, or GDPR controls are being enforced in the new environment. Manual tracking gets harder across multiple accounts or regions, and missteps, like missing encryption, improper access logging, or insecure storage, can result in violations and penalties.
The fix: Maintaining compliance in AWS requires continuous monitoring, not just upfront configuration:
- Enable AWS CloudTrail to log all account activity and API calls. This creates a detailed audit trail for compliance audits.
- Use AWS Config and managed Config Rules to automatically track whether resources like Amazon S3, RDS, and IAM follow the compliance baseline (e.g., encryption enabled, public access blocked).
- Set up conformance packs for specific frameworks like HIPAA or PCI-DSS to apply a consistent set of controls across accounts.
- Use the AWS Well-Architected Tool, specifically the Security Pillar, to review workloads before and after migration for policy alignment and security gaps.
How one SMB handled it: A mid-sized healthtech company moved its appointment scheduling system to AWS. They assumed compliance would carry over, but a review showed their Amazon S3 backups lacked encryption and IAM roles had excessive permissions. Working with an AWS partner, they enabled Config Rules to enforce encryption and AWS CloudTrail for tracking changes. They also ran an Amazon Well-Architected review to close remaining gaps, helping them meet HIPAA standards before relaunch.
Challenge 7: Lack of cloud security expertise
For many SMBs, in-house IT teams are strong on traditional infrastructure but haven’t had the time or budget to go deep on cloud security. This creates blind spots during migration, especially around the shared responsibility model, IAM configuration, and native tools like CloudTrail or Security Hub. Without that context, it’s easy to miss critical setup steps or misconfigure access and logging.
The fix: Bridging the knowledge gap early helps avoid security missteps:
- Start with AWS’s free training modules on cloud security fundamentals to ground the team in core concepts.
- Use the AWS Shared Responsibility Model as a guide to define exactly what the team is responsible for versus what AWS secures.
- Involve a certified AWS Partner like Cloudtech during the planning phase. They can help design secure landing zones, set guardrails, and handle configurations that may be unfamiliar to internal teams.
- Establish a security review checkpoint for each migration phase, including planning, testing, and cutover.
How one SMB handled it: A regional payroll service moving off legacy servers wasn’t familiar with IAM best practices or how to use AWS CloudTrail. They worked with an AWS partner to define scoped roles, implement least privilege policies, and enable centralized logging across accounts. As a result, they avoided costly misconfigurations, and their internal team gained confidence by learning alongside the migration.
Challenge 8: Inconsistent security across hybrid environments
Many SMBs don’t move everything to the cloud at once. For months, or even years, they run in a hybrid model, with some systems still on-premises while others operate in AWS. The problem? Security policies often evolve separately. SMBs might have strong IAM rules and logging in AWS, but loose firewall rules or missing audit trails on-prem. That gap creates room for lateral attacks, especially if identity and access aren’t unified.
The fix: To secure hybrid environments, SMBs need to standardize their security posture across both legacy and cloud systems:
- Use AWS Organizations with Service Control Policies (SCPs) to enforce guardrails across all AWS accounts from day one.
- Deploy AWS GuardDuty for real-time threat detection and anomaly alerts across cloud workloads.
- Integrate CloudTrail logs with on-prem SIEM tools or set up AWS Security Hub to centralize findings across environments.
- For identity, consider extending Active Directory to AWS using AWS Directory Service to maintain consistent user access policies.
How one SMB handled it: A mid-sized manufacturing firm moved its CRM and analytics stack to AWS but kept its ERP on local servers. Initially, access to cloud apps required MFA, but ERP access was unchanged. After a minor breach via a compromised ERP credential, they worked with an AWS partner to align IAM, deploy GuardDuty, and use Security Hub to monitor both sides. That consistency helped shut down potential gaps, and passed their next audit without issues.
Challenge 9: DevOps speed outpacing security
For SMBs adopting DevOps, the shift to rapid releases and automated deployments is a big win. But that speed can outpace security. Developers may push code that includes hardcoded secrets, misconfigured IAM roles, or unvetted open-source libraries, often without security teams catching it until after deployment. In small teams, security reviews are sometimes skipped entirely to meet deadlines.
The fix: Security needs to be embedded early in the software delivery pipeline, not bolted on after deployment:
- Integrate static application security testing (SAST) tools like SonarQube or Amazon CodeGuru Reviewer into the CI/CD process.
- Use AWS Secrets Manager to eliminate hardcoded secrets in source code.
- Add IAM policy linting with tools like CloudFormation Guard or IAM Access Analyzer to validate roles before they're deployed.
- Apply pre-deployment scanning using Amazon Inspector for EC2 or container images.
How one SMB handled it: A SaaS startup was deploying updates twice a week, but after an incident involving an exposed API key in Git, they realized speed was coming at a cost. By embedding CodeGuru, Secrets Manager, and policy validation into their CI/CD pipelines, they caught risky changes early without slowing down releases.
Challenge 10: Cloud-to-cloud migrations without revalidation
When SMBs migrate workloads between cloud providers, or even between AWS accounts, they often assume existing security settings will carry over. But policies, encryption keys, and IAM roles don’t always translate as one might expect. This can result in missing resource-level permissions, broken encryption, or inadvertently exposed services. Something as simple as forgetting to reapply an Amazon S3 bucket policy in a new account can make private data public.
The fix: Treat every cloud-to-cloud migration as a clean slate for security. That means:
- Re-auditing all IAM roles, bucket policies, and VPC settings post-migration.
- Rotating credentials and API keys to invalidate old access paths.
- Using AWS IAM Access Analyzer and AWS Config to validate resource sharing and compliance in the new environment.
- Running automated validation scripts to confirm encryption settings (via KMS), security groups, and ACLs are correctly enforced.
- Conducting a post-migration security audit, ideally with help from a partner or AWS Well-Architected Framework review.
How one SMB handled it: A fintech SMB moved their analytics pipeline from one AWS account to another to separate environments by function. After the migration, data from an Amazon S3 bucket became accessible publicly due to a missing policy reattachment. They avoided a breach thanks to an automated Config rule that flagged the misconfiguration within minutes, but it was a close call. Post-migration auditing is now part of every internal change request.
Pro tip: Working with an AWS Partner gives SMBs access to specialized cloud security expertise that internal teams may not have. Partners can spot hidden risks early, before they lead to misconfigurations, compliance gaps, or downtime. Their experience across similar migrations helps implement preventive controls from day one, not after issues arise.

How to successfully set up and manage Amazon S3 Glacier storage?
Setting up Amazon S3 Glacier storage classes requires careful planning of bucket configurations, lifecycle policies, and access management strategies. Organizations must consider data classification requirements, access patterns, and compliance obligations when designing Amazon S3 Glacier storage implementations.
The management approach differs significantly from standard Amazon S3 storage due to retrieval requirements and cost optimization considerations. Proper configuration ensures optimal performance while minimizing unexpected costs.
Step 1: Creating and configuring Amazon S3 buckets
S3 bucket configuration for Amazon S3 Glacier storage classes requires careful consideration of regional placement, access controls, and lifecycle policy implementation. Critical configuration parameters include:
- Regional selection: Choose regions based on data sovereignty requirements, disaster recovery strategies, and network latency considerations for retrieval operations
- Access control policies: Implement IAM policies that restrict retrieval operations to authorized users and prevent unauthorized cost generation
- Versioning strategy: Configure versioning policies that align with minimum storage duration requirements (90 days for Instant/Flexible, 180 days for Deep Archive)
- Encryption settings: Enable AES-256 or AWS KMS encryption for compliance with data protection requirements
Bucket policy configuration must account for the restricted access patterns associated with Amazon S3 Glacier storage classes. Standard S3 permissions apply, but organizations should implement additional controls for retrieval operations and related costs.
Step 2: Uploading and managing data in Amazon S3 Glacier storage classes
Direct uploads to Amazon S3 Glacier storage classes utilize standard S3 PUT operations with appropriate storage class specifications. Key operational considerations include:
- Object size optimization: AWS applies default behavior, preventing objects smaller than 128 KB from transitioning to avoid cost-ineffective scenarios
- Multipart upload strategy: Large objects benefit from multipart uploads, with each part subject to minimum storage duration requirements
- Metadata management: Implement comprehensive tagging strategies for efficient object identification and retrieval planning
- Aggregation strategies: Consider combining small files to optimize storage costs, where minimum duration charges may exceed data storage costs
Large-scale migrations often benefit from AWS DataSync or AWS Storage Gateway implementations that optimize transfer operations. Organizations should evaluate transfer acceleration options for geographically distributed data sources.
Step 3: Restoring objects and managing retrieval settings
Object restoration from Amazon S3 Glacier storage classes requires explicit restoration requests that specify retrieval tiers and duration parameters. Critical operational parameters include:
- Retrieval tier selection: Choose appropriate tiers based on urgency requirements and cost constraints
- Duration specification: Set restoration duration (1-365 days) to match downstream processing requirements
- Batch coordination: Plan bulk restoration operations to avoid overwhelming downstream systems
- Cost monitoring: Track retrieval costs across different tiers and adjust strategies accordingly
Restored objects remain accessible for the specified duration before returning to the archived state. Organizations should coordinate restoration timing with downstream processing requirements to avoid re-restoration costs.
How to optimize storage with Amazon S3 Glacier lifecycle policies?
Moving beyond basic Amazon S3 Glacier implementation, organizations can achieve significant cost optimization through the strategic configuration of S3 lifecycle policies. These policies automate data transitions across storage classes, eliminating the need for manual intervention while ensuring cost-effective data management throughout object lifecycles.
Lifecycle policies provide teams with precise control over how data is moved across storage classes, helping to reduce costs without sacrificing retention goals. For Amazon S3 Glacier, getting the configuration right is crucial; even minor missteps can result in higher retrieval charges or premature transitions that impact access timelines.
Translating strategy into measurable savings starts with how those lifecycle rules are configured.
1. Lifecycle policy configuration fundamentals
Amazon S3 lifecycle policies automate object transitions through rule-based configurations that specify transition timelines and target storage classes. Organizations can implement multiple rules within a single policy, each targeting specific object prefixes or tags for granular control and management.
Critical configuration parameters include:
- Transition timing: Objects in Standard-IA storage class must remain for a minimum of 30 days before transitioning to Amazon S3 Glacier
- Object size filtering: Amazon S3 applies default behavior, preventing objects smaller than 128 KB from transitioning to avoid cost-ineffective scenarios
- Storage class progression: Design logical progression paths that optimize costs while maintaining operational requirements
- Expiration rules: Configure automatic deletion policies for objects reaching end-of-life criteria
2. Strategic transition timing optimization
Effective lifecycle policies require careful analysis of data access patterns and cost structures across storage classes. Two-step transitioning approaches (Standard → Standard-IA → Amazon S3 Glacier) often provide cost advantages over direct transitions.
Optimal transition strategies typically follow these patterns:
- Day 0-30: Maintain objects in the Standard storage class for frequent access requirements
- Day 30-90: Transition to Standard-IA for reduced storage costs with immediate access capabilities
- Day 90+: Implement Amazon S3 Glacier transitions based on access frequency requirements and cost optimization goals
- Day 365+: Consider Deep Archive transition for long-term archival scenarios
3. Policy monitoring and cost optimization
Billing changes occur immediately when lifecycle configuration rules are satisfied, even before physical transitions complete. Organizations must implement monitoring strategies that track the effectiveness of policies and their associated costs.
Key monitoring metrics include:
- Transition success rates: Monitor successful transitions versus failed attempts
- Cost impact analysis: Track storage cost reductions achieved through lifecycle policies
- Access pattern validation: Verify that transition timing aligns with actual data access requirements
- Policy rule effectiveness: Evaluate individual rule performance and adjust configurations accordingly

SMBs serving content to customers across regions can connect Amazon S3 to Amazon CloudFront, AWS’s content delivery network (CDN).
How it works: Amazon S3 acts as the origin, and Amazon CloudFront caches content in AWS edge locations to reduce latency.
Example: A regional telehealth provider uses Amazon CloudFront to quickly deliver patient onboarding documents stored in Amazon S3 to remote clinics, improving access speed by over 40%.
- On-demand data querying with Amazon Athena
Amazon Athena lets teams run SQL queries directly on Amazon S3 data without moving it into a database.
How it helps: No need to manage servers or build data pipelines. Just point Amazon Athena to Amazon S3 and start querying.
Example: A diagnostics lab uses Athena to run weekly reports on CSV-formatted test results stored in S3, without building custom ETL jobs or infrastructure.
- Event-driven automation using AWS Lambda
AWS Lambda can be triggered by Amazon S3 events, like new file uploads, to automate downstream actions.
Use case: Auto-processing medical images, converting formats, or logging uploads in real-time.
Example: When lab reports are uploaded to a specific Amazon S3 bucket, an AWS Lambda function instantly routes them to the right physician based on metadata.
- Centralized backup and archival with AWS Backup and S3 Glacier
Amazon S3 integrates with AWS Backup to enforce organization-wide backup policies and automate lifecycle transitions.
Benefits: Meets long-term retention requirements, such as HIPAA or regional health regulations, without manual oversight.
Example: A healthcare SMB archives historical patient data from Amazon S3 to Amazon S3 Glacier Deep Archive, retaining compliance while cutting storage costs by 40%.
- Strengthened data security with Amazon Macie and Amazon GuardDuty
Amazon Macie scans S3 for sensitive information like PHI or PII, while Amazon GuardDuty detects unusual access behavior.
How it helps: Flags risks early and reduces the chance of breaches.
Example: A health records company uses Amazon Macie to monitor Amazon S3 buckets for unencrypted PHI uploads. Amazon GuardDuty alerts the team if unauthorized access attempts are made.
These integrations make Amazon S3 a foundational service in any SMB’s modern cloud architecture. When configured correctly, they reduce operational burden, improve security, and unlock value from stored data without adding infrastructure complexity.

Best practices SMBs can follow to optimize Amazon S3 benefits
For small and mid-sized businesses, maximizing both time and cost efficiency is critical. Simply using Amazon S3 for storage isn’t enough. Businesses must fine-tune their approach to get the most out of it. Here are several best practices that help unlock the full potential of Amazon S3:
- Use smarter naming to avoid performance bottlenecks: Sequential file names like invoice-001.pdf, invoice-002.pdf can overload a single partition in Amazon S3, leading to request throttling. By adopting randomized prefixes or hash-based naming, businesses can distribute traffic more evenly and avoid slowdowns.
- Split large files using multipart uploads: Uploading large files in a single operation increases the risk of failure due to network instability. With multipart uploads, Amazon S3 breaks files into smaller parts, uploads them in parallel, and retries only the failed parts. This improves speed, reliability, and reduces operational frustration.
- Reduce latency for distributed users: For SMBs with global teams or customer bases, accessing data directly from Amazon S3 can introduce delays. By integrating Amazon CloudFront, data is cached at edge locations worldwide, reducing latency and improving user experience.
- Accelerate long-distance transfers: When remote offices or partners need to send large volumes of data, Amazon S3 Transfer Acceleration uses AWS’s edge infrastructure to speed up uploads. This significantly reduces transfer time, especially from distant geographies.
- Monitor usage with Amazon CloudWatch: Tracking S3 performance is essential. Amazon CloudWatch offers real-time visibility into metrics such as request rates, errors, and transfer speeds. These insights help businesses proactively resolve bottlenecks and fine-tune performance.
By applying these practices, SMBs transform Amazon S3 from a basic storage tool into a powerful enabler of performance, cost-efficiency, and scalability.
