For startup CTOs
You're shipping fast. You need security that doesn't slow your team down — and a pentest that finds real issues before your enterprise customers' security team does.

Who we work with
For mid-market security leads
You need senior offensive and defensive expertise without the enterprise-consultancy overhead. We bring banking-grade methodology to teams that need real depth without an army of analysts behind it.
For teams shipping AI
Your LLM and agentic systems are a new attack surface most pentest firms don't understand. We red-team them with the same rigor we apply to traditional infrastructure.
Practice areas
Both sides of the security table.
Most firms pick one side. We don't. Penetration testing, red-team operations, and AI / LLM security on the offensive side — Kubernetes security, cloud security, and DevSecOps on the defensive side. One firm. Full lifecycle.
01 Offensive
Penetration Testing
Manual, senior-led exploitation for internet-reachable web applications and REST/GraphQL APIs. First engagement: we find a high-severity vulnerability or you don’t pay.
Learn more
02 Offensive
Red Teaming
Goal-based engagements that simulate how a real attacker would move through your environment. MITRE ATT&CK-aligned.
Learn more
03 Offensive
AI & LLM Security
Red-teaming for LLM applications, agentic systems, and the APIs they touch. The risks most pentest firms don't test for.
Learn more
04 Defensive
Kubernetes Security
Cluster hardening, CIS benchmarks, admission control, supply-chain security, and runtime defense. CKS-led.
Learn more
05 Defensive
DevSecOps
Pipeline-integrated SAST, DAST, SCA, and IaC scanning. Secrets management. Security as a CI step, not a quarterly review.
Learn more
06 Defensive
Cloud Security
Azure and AWS security architecture, IAM modernization, Zero Trust design, and least-privilege workload identity.

Security Training & Workshops
The fastest way to harden a team is to have them break things in a controlled environment, then fix them. Our workshops are hands-on, lab-driven, and taught by the same senior practitioners who run our offensive and defensive engagements — not trainers reading from a slide deck.

Methodology
Five steps. Five things you walk away with.
We don't sell hours — we sell deliverables. Every CAASLABS engagement, no matter the service, follows the same five steps and produces the same five things. You'll know exactly what you're getting before you sign, and exactly what's landing in your inbox at every stage.
- Step 01Written scope
Scope
A written engagement scope before any work begins. Targets, exclusions, success criteria, communication cadence, and emergency contacts. You sign it. We sign it. No surprises, no scope creep.
- Step 02Attack surface map
Reconnaissance & baseline
We map what's actually exposed — not what your asset inventory says is exposed. For offensive engagements, that's an external attack surface map. For DevSecOps engagements, that's a CIS-aligned baseline of your cloud, Kubernetes, and CI/CD posture.
- Step 03Daily updates
Execution
Penetration testing, red-team operations, hardening work, or pipeline integration — whatever the engagement called for. Daily updates in your Slack or email. Zero ghosting. Critical findings reported within 24 hours of discovery, not buried in a final PDF.
- Step 04Two reports
Reporting
Two reports, not one: a technical report with reproduction steps, evidence, and remediation guidance your engineers can act on, and an executive summary your board can read in five minutes. Sample format available on request before you sign.
- Step 05Verification retest
Retest & handoff
A verification retest pass on every critical and high finding. We verify each one is actually closed — not just marked resolved in a ticket. The 60-day retest clock starts the day we deliver the report: you request the retest in writing by day 45, and we complete it by day 60. The 15-day buffer exists because senior practitioners are scheduled in advance against other engagements and the same practitioner who ran the original test should run the retest while environmental context — network topology, tenant structure, tooling state — is still fresh. Included in every offensive and audit engagement (pentesting, red teaming, AI red teaming, and Kubernetes security), no separate SOW.
Operational discipline
Your engagement won't show up in our marketing.
Red-team and offensive engagements depend on operational discipline, and that discipline starts with the team that runs them. No founder photos. No LinkedIn handles tied to client work. No case studies on our homepage in six months. Our operators don't carry public profiles tied to client engagements — and that's intentional. You'll meet your senior lead on the discovery call, under NDA, before any work begins. We'd rather earn your trust on a call than perform it on a homepage.
Our commitments
How we work with you. In writing.
01
Senior-led from day one
Every engagement is run by a credentialed senior specialist. No shadow teams, no offshore handoffs, no mystery consultants on the Slack channel.
02
Written scope before kickoff
You'll know exactly what we're doing — and what we're not — before any work begins. Targets, exclusions, success criteria, and communication cadence, all signed by both sides.
03
Verification retest within 60 days of report delivery
We run a verification retest of every critical and high finding to confirm each one is actually closed — not just marked resolved in a ticket. The 60-day clock starts the day we deliver the report; you request the retest in writing by day 45 and we complete it by day 60. Included in every offensive and audit engagement.
Frequently asked
- Who is CAASLABS for?
- Startups, scale-ups, and mid-market engineering teams who need senior-led cybersecurity services — penetration testing, red teaming, AI security, Kubernetes hardening, DevSecOps, and cloud security. Every engagement is run by a credentialed practitioner, not an offshore review layer.
- How is CAASLABS different from other cybersecurity firms?
- Three things: every engagement is senior-led (OSCP+, CKS, AZ-500, AWS Security Specialty), we test AI/LLM applications as a core service — not an afterthought — and you get a verification retest of every critical and high finding within 60 days at no extra cost.
- What does a 30-minute diagnostic call look like?
- A direct conversation with a senior specialist — no SDRs, no demo decks, no scripts. We'll discuss what you're building, where you think the risk is, and whether an engagement makes sense. If it doesn't, we'll tell you.
- How long does a typical penetration test take?
- Most web or API engagements run 1–3 weeks of active testing, followed by 3–5 business days for reporting. Larger scopes (multi-app, infrastructure plus cloud) run 3–6 weeks. Every engagement is scoped in writing before kickoff.
- Do you work with companies preparing for SOC 2 or ISO 27001?
- Yes — compliance-driven engagements are a large part of what we do. We deliver pentest reports that auditors accept, and we scope the engagement to cover exactly what your compliance framework requires.
- Can you test AI and LLM applications?
- Yes. We red-team LLM applications, agentic systems, and RAG pipelines against the OWASP LLM Top 10 — prompt injection, jailbreak resilience, tool-use abuse, data exfiltration, and model supply-chain risks. Most traditional pentest firms do not offer this.
