Architecture Documentation for Security Teams

Get architecture visibility for threat modeling, compliance audits, and incident response.

Architecture visibility for security and compliance

Security audits start with understanding what exists. Archyl gives your security team a living map of systems, data flows, and dependencies -- so threat modeling, compliance audits, and incident response start from reality, not guesswork.

No complete picture of the attack surface

You cannot protect what you do not know exists. Without a current architecture map, threat modeling is based on incomplete information.

Compliance audits require architecture evidence

SOC 2, ISO 27001, and GDPR auditors ask for system architecture documentation. Producing it manually is time-consuming and instantly outdated.

Incident response wastes time on discovery

When a breach occurs, the first hours are spent understanding what systems are affected and how they connect, instead of containing the incident.

Data flows are undocumented

You need to know where PII flows, which services handle payment data, and what external APIs are called. This information is scattered across teams.

AI maps the real architecture

Connect repositories and let AI discover all systems, services, databases, and their communication patterns. Get a complete map of what actually exists.

C4 model shows data flows and boundaries

Visualize system boundaries, trust zones, and data flows at four levels of detail. Use overlays to highlight security-relevant information.

Conformance rules enforce security standards

Define rules like 'all external APIs must go through the API gateway' or 'databases must not be publicly accessible.' Automated checks detect violations.

Drift detection catches shadow infrastructure

When developers add new services or external dependencies without updating documentation, drift detection flags them so nothing goes unnoticed.

ADRs Document Security Decisions

Record security-related architecture decisions with full context. Link ADRs to the specific C4 elements they affect for traceability.

Create custom overlays showing trust boundaries, data classification, encryption status, or compliance scope on top of your C4 diagrams.

Query Architecture from AI Tools

Security engineers can ask their AI assistant questions like 'What services handle PII?' or 'Show me all external integrations' through MCP tools.

Alerts on Architecture Changes

Get notified when architecture changes occur that might affect security posture. Review and approve changes before they go live.

Architecture Change Review

Security team can be included in architecture change request reviews. No infrastructure change goes unreviewed.

Technology Risk Visibility

The technology radar shows which technologies are in use across the organization. Identify end-of-life software and unsupported dependencies.
