Overview
Resilience Built In, Not Bolted On
Confidently strengthen your AWS security and resilience with a business-aligned assessment that uncovers risks and defines clear recovery improvements - delivered in just three hours of your team's time.
As cloud environments evolve, resilience and security often drift - leaving recovery expectations misaligned and risks hidden until disruption strikes. The Resilience and Security Assessment (RSA), developed by AWS and delivered by Zen as an AWS Advanced Services Partner, provides a structured, expert-led review that maps your environment against the AWS Well-Architected Framework, including the Security and Reliability Pillars.
Who This Is For
RSA is ideal for organisations running production workloads on AWS where unplanned downtime carries regulatory or revenue consequences - particularly in financial services, healthcare, and other regulated industries. Whether you operate a single critical workload or a multi-account landing zone, RSA scales to your needs.
What We Assess
Our assessment leverages and reviews your use of key AWS services including:
- AWS Resilience Hub - validating recovery policies and resilience posture
- AWS Backup - evaluating backup strategies against stated RTO/RPO targets
- AWS Security Hub - reviewing security findings and compliance status
- AWS Config - assessing configuration drift and rule compliance
- AWS CloudTrail - verifying audit logging and incident traceability
Engagement Scope and Prerequisites
Scope: The standard RSA covers a defined set of workloads within a single AWS account or a scoped multi-account environment. The number of workloads assessed is agreed during a pre-engagement discovery call.
Prerequisites: Customers should have architecture documentation or diagrams available and provide read-only access to relevant AWS accounts. Key participants should include a technical lead (e.g., platform engineer or architect) and a business stakeholder (e.g., CTO, Head of IT, or business continuity owner).
Exclusions: RSA does not include penetration testing, compliance certification, or hands-on remediation (though optional accelerated remediation is available as a follow-on engagement).
How It Works
- Pre-engagement discovery - A short intake call to define scope, gather context, and confirm participants.
- Architecture review - In-depth workload assessment against AWS resilience, recovery, and security best practices.
- Gap analysis - Identify misaligned RTO/RPOs, resilience drift, and hidden vulnerabilities mapped against the AWS Well-Architected Security Pillar and Reliability Pillar.
- Business alignment - Unify executive and technical priorities through tailored planning sessions.
- Actionable roadmap - Clear, prioritised next steps delivered as a written report, with optional accelerated remediation for quick wins.
Benefits
Stronger recovery capability - Identify and close gaps in RTO and RPO, ensuring your AWS environment can recover at the speed your business expects - not the pace legacy designs allow.
Reduced security risk - Uncover hidden vulnerabilities and misconfigurations, then align security controls to business needs and recognised frameworks to reduce exposure and strengthen your overall security posture.
Clear executive alignment - Bring business continuity and technical priorities together. Ensure decision-makers and technical teams are aligned on risks, recovery, and security improvements that protect revenue and reputation.
Action you can trust - Leave with a tailored, prioritised plan that focuses effort where it matters most, backed by expert guidance from Zen's UK-based team and optional hands-on support to accelerate improvements.
Why Zen
As an AWS Advanced Services Partner, Zen brings deep AWS specialisation and a UK-based team that works closely with customers for long-term, consistent results. Unlike broad security audits that take weeks and deliver generic reports, RSA is designed to deliver actionable clarity in just three hours of your team's time - making it one of the fastest paths from uncertainty to a defensible resilience posture.
To get started, book a discovery call or contact our team to discuss your requirements.
Highlights
- Expert-led AWS resilience and security assessment delivered in just three hours of customer time - versus the typical multi-week engagement cycle. Zen's structured approach, developed with AWS, maps your workloads against the AWS Well-Architected Framework to identify critical RTO/RPO gaps, security misconfigurations, and resilience drift rapidly and efficiently.
- Alignment of business continuity objectives (RTO/RPO) with technical implementation across key AWS services including AWS Resilience Hub, AWS Backup, and AWS Security Hub. The assessment bridges the gap between executive recovery expectations and actual platform capability, ensuring decision-makers and engineers share a common view of risk.
- Tailored, prioritised action plan focused on immediate business impact, delivered as a written report with clear next steps. Unlike generic audit outputs, the roadmap ranks findings by business severity and includes optional accelerated remediation support from Zen's UK-based team to help you act on critical gaps immediately.

Engagement Process
Getting started: Contact Zen's team to schedule a pre-engagement discovery call where we define scope, confirm participants, and gather initial context about your AWS environment.
During the engagement: The RSA workshop requires approximately three hours of your team's time. Recommended attendees include a technical lead (platform engineer or architect) and a business stakeholder (CTO, Head of IT, or business continuity owner). Customers should have architecture documentation available and provide read-only access to relevant AWS accounts.
Deliverables: Following the workshop, you will receive a written report containing a prioritised action plan with findings ranked by business severity, along with clear next steps and optional remediation recommendations.
Timeline: The total elapsed time from discovery call to final deliverable handoff is typically completed within two weeks, depending on scheduling availability.
Post-Engagement Support
After deliverable handoff, Zen's UK-based team is available to answer clarification questions about the report and discuss follow-on remediation options.
