Continuous Security Coverage. Not Annual Checkbox Testing.
Guardian retainers deliver ongoing AI security testing, quarterly assessments, CI/CD integration review, and monthly advisory — so your security posture keeps pace with your AI deployment.
You might be experiencing...
Annual penetration testing was designed for infrastructure that changes annually. AI stacks change weekly.
New agents deployed. New tools integrated. New prompt templates shipped. New LLM model versions adopted. Each change introduces new attack surface. An annual test is a snapshot of a moment that no longer exists.
Why Continuous Coverage Matters for AI
AI agents are not static targets. A prompt injection vulnerability that didn’t exist three months ago exists today because your engineering team shipped a new system prompt. A tool poisoning vector that didn’t exist last quarter exists today because your agent now calls a new API.
The Guardian Security Retainer provides the continuous coverage that the pace of AI deployment demands:
- Pre-deployment reviews catch security issues before they reach production — not after a breach
- CI/CD integration reviews assess the security posture of new AI features at the pipeline level, not just at the application layer
- Monthly advisory keeps your team informed of new AI-specific attack techniques as they emerge
- Quarterly assessments provide the structured compliance evidence that auditors expect
- Named researcher gives your security team a direct line to AI security expertise without building an internal AI red team
The Continuous Testing Compliance Case
ISO 27001, SOC 2 Type II, and the NIST AI Risk Management Framework all require evidence of ongoing security management — not a single annual snapshot. The Guardian retainer produces that evidence continuously:
- Quarterly penetration assessment reports satisfy the periodic testing requirements of ISO 27001 A.8.8 and SOC 2 CC7.1
- Monthly advisory sessions and threat intelligence briefings demonstrate active security management
- Pre-deployment reviews create documented evidence that new AI features were security-reviewed before release
- The annual compliance evidence package bundles all Guardian deliverables into a format ready for auditor review
For engineering teams working toward SOC 2 Type II certification, the Guardian retainer provides the 12 months of continuous evidence that Type II assessors require — structured, consistent, and auditor-ready.
The CI/CD Integration Advantage
Guardian retainers include CI/CD integration review for new AI features — a unique capability that goes beyond traditional security retainers. When your engineering team deploys a new AI agent, integrates a new tool, or changes a system prompt at scale, your named researcher reviews the change from a security perspective before it reaches production.
This is not a replacement for automated security gates in your pipeline — it is the human expert layer above them. Automated gates catch known vulnerability patterns. Your named researcher catches the architectural decisions, permission grants, and trust relationships that automated tools cannot evaluate.
For engineering teams that have implemented Security QA Integration (automated security gates), the Guardian retainer provides the complementary human expert layer — automated breadth, human depth, continuous coverage.
Engagement Phases
Onboarding
Full initial assessment of your AI stack, attack surface baseline, security posture benchmark, Guardian program setup.
Continuous Coverage
Monthly advisory sessions, continuous threat intelligence relevant to your stack, ad-hoc testing of new AI features before deployment.
Quarterly Assessment
Structured penetration assessment of your full AI attack surface. New findings report, remediation tracking, posture delta from baseline.
Annual Review
Full-year security posture review, comprehensive findings summary, compliance evidence package, program renewal assessment.

Tools We Use
Frequently Asked Questions
What tiers does Guardian offer?
Guardian Core provides quarterly scans, monthly briefings, and 8 hours of advisory per month — designed for engineering teams that need baseline continuous coverage. Guardian Pro adds semi-annual penetration tests, compliance monitoring, and security champion support. Guardian Enterprise provides continuous AI testing, incident response retainer, and CISO-level advisory. We scope the right tier based on your AI stack size, compliance requirements, and risk profile.
What is the minimum contract term?
Guardian retainers are structured as 12-month programs. The first month includes full onboarding assessment. Month-to-month arrangements are available for engineering teams completing a trial period before annual commitment.
What happens when a vulnerability is found?
Critical and high-severity findings are reported within 48 hours of discovery — not held until the quarterly report. Your named researcher contacts your security team directly with findings, reproduction steps, and initial remediation guidance. Critical findings include emergency advisory support at no additional cost.
Can we upgrade tiers mid-program?
Yes. Guardian tier upgrades take effect at the next billing cycle. Many engineering teams start at Guardian Core after an initial assessment engagement and upgrade to Guardian Pro as their AI deployment grows.
Do I need written authorization?
Yes. Written authorization from a person with legal authority over all systems in scope is mandatory before testing begins. We provide a standard Authorization to Test (ATT) document covering the full Guardian program scope, including all systems that may be tested during the retainer period.
