AWS Infrastructure Assessment for a Cybersecurity SaaS

The Client is a AI-native security platform that provides a Security Operating System for leaders and organizations that need to manage cybersecurity programs. The platform helps companies simplify security management, assess risk, manage compliance, track suppliers, handle security metrics, and work across frameworks such as ISO 27001, NIST CSF, SOC 2, PCI DSS, and others.

As the Client’s AWS environment grew across multiple accounts, the Company needed stronger visibility into how well its infrastructure was governed, protected, and prepared for operational risks. The Client had to make sure that production and shared infrastructure were configured consistently, followed AWS best practices, and did not contain gaps that could affect availability, compliance, or day-to-day operations.

Without an independent review, potential misconfigurations, weak controls, or architectural gaps could remain unnoticed and become harder to address as the environment continued to grow.

Romexsoft’s AWS-certified DevOps engineers worked with Infotrust to assess the Client’s cloud environment across security, governance, architecture, networking, availability, data protection, monitoring, and operational readiness.

Key Assessment Areas

Our DevOps team reviewed the AWS environment to identify configuration, control, and architectural gaps that could affect operational stability and long-term maintainability.

• Access control
  This part of the assessment focused on IAM configuration, access patterns, security groups, secrets management, encryption, and storage protection. The goal was to identify permissions, exposure points, or credential-handling practices that could increase security risk.
• Cloud governance
  The assessment reviewed AWS Organizations, account structure, CloudFormation, and Infrastructure as Code practices to understand how the Client governed resources across production and shared environments, controlled infrastructure changes, and maintained consistency across accounts.
• Network architecture and workload resilience
  We evaluated VPC design, Transit Gateway configuration, EC2, Auto Scaling, Load Balancers, and high availability settings to understand how well the environment handled traffic, segmentation, workload stability, and potential infrastructure failures.
• Data protection and recovery readiness
  Amazon RDS, Amazon S3, backups, logging, encryption, and disaster recovery practices were assessed to determine how well the environment protected business-critical data and supported recovery in case of failure or incident.
• Monitoring and threat visibility
  CloudTrail, CloudWatch, GuardDuty, Security Hub, Macie were reviewed to check whether our Client had enough visibility into infrastructure activity, operational issues, and potential vulnerabilities.

Key Findings

The assessment showed that the Company’s AWS environment needed targeted improvements in security control, resilience, visibility, and operational governance.

• Tighter control over sensitive assets and infrastructure access was needed across IAM, secrets, credentials, storage, and encryption. Addressing these gaps would reduce exposure risks and strengthen security and compliance readiness.
• Stronger network isolation and more restrictive access paths would help reduce the attack surface and limit unnecessary exposure between infrastructure components.
• Configuration-level improvements to availability and workload resilience were required to reduce the risk of service disruption in production.
• Broader monitoring, logging, and threat detection coverage would enable earlier issue detection, faster event investigation, and more effective incident response.
• Clearer infrastructure lifecycle controls and operational processes would help clients maintain consistency, reduce manual effort, and manage its AWS environment more predictably as the platform evolves.

Deliverables

The Company received a structured set of deliverables that turned the assessment results into a clear improvement plan:

• Infrastructure assessment report with a detailed overview of the reviewed AWS environment, identified gaps, and risk areas.
• Prioritized gap register with severity classification to help the Client understand which issues required immediate attention and which could be planned for later.
• Remediation recommendations for each finding, focused on practical improvements to security, resilience, governance, and operational control.
• Implementation roadmap organized around critical, high, and medium-priority improvements, helping our Client plan remediation work in the right order.
• AWS best-practice guidance aligned with security and operational standards to support long-term cloud readiness.

The assessment gave the Client a clear, risk-based view of its AWS environment and helped understand which infrastructure gaps required priority attention.

Delivered in cooperation with Infotrust, Romexsoft’s DevOps expertise helped translate technical findings into practical remediation priorities. Instead of receiving a generic list of issues, the company got a structured view of what could affect availability, governance, and operational stability, and which improvements should come first.

Our Client could use the assessment results to plan remediation more confidently, align infrastructure improvements with business risk, and define the next steps for strengthening security, resilience, and operational maturity as the platform continues to grow.
