Penetration testing services

Manual testing across four surfaces — web apps, APIs, networks and AI. Each engagement is fixed scope and fixed price, delivered by senior testers: the people you talk to are the people who test.

Web Application Penetration Testing

Manual, exploitation-first

We test your application as an attacker with a browser and a proxy. Not a crawler.

What we test

  • Authentication and session management
  • Authorization, IDOR and privilege escalation
  • Injection: SQL, command, template, SSRF
  • Business logic and workflow abuse
  • Client-side: XSS, CSP bypasses, prototype pollution
  • Cryptography and token handling

How we work

  • Map roles, endpoints and trust boundaries.
  • Test each role against every privileged action.
  • Chain low-severity issues into real impact.
  • Validate manually before reporting.

API Penetration Testing

REST, GraphQL, SOAP

APIs fail differently than UIs. We test the contract, not the screens built on top of it.

What we test

  • Object-level and function-level authorization
  • Token lifecycle, JWT weaknesses, session flaws
  • Mass assignment and request-body tampering
  • Injection and deserialization paths
  • Rate limiting and abuse scenarios
  • Verbose errors and leaked secrets

How we work

  • Enumerate every endpoint, including undocumented ones.
  • Replay each call across role and tenant boundaries.
  • Probe business rules: pricing, limits, workflows.
  • Confirm impact before it reaches the report.

Network Penetration Testing

External and internal

External: what the internet can reach. Internal: what one compromised laptop can reach. We test both as separate scopes or one program.

What we test

  • Perimeter: firewalls, VPNs, exposed services, cloud front doors
  • Internal: segmentation, lateral movement, credential paths
  • Privilege escalation and domain takeover routes
  • Weak protocols and configurations: SMB, RDP, SSH, DNS
  • Reach to sensitive data and critical applications

How we work

  • Discover and map reachable assets and services.
  • Manually verify settings and exposed functions.
  • Build practical attack chains, not CVE lists.
  • Simulate the attacker position after first entry.

AI & LLM Penetration Testing

Models, agents, RAG pipelines

Your AI product has an attack surface: prompts, tools, retrieval stores, memory. Most security teams have never tested any of it.

What we test

  • Prompt injection and hidden directives
  • Jailbreaks and guardrail bypass
  • RAG poisoning and retrieval abuse
  • Tool and function-call abuse, escalated authority
  • Data leakage: secrets, PII, system prompts
  • Model and vendor configuration weaknesses

How we work

  • Gather architecture and usage context.
  • Map trust edges and abuse routes.
  • Run adversary-style checks against live flows.
  • Validate impact, spread and escalation.

Compliance and due diligence

Reports built to satisfy auditors and customer security reviews, not just to fill a folder.

  • SOC 2 — evidence of an annual, independent penetration test.
  • ISO 27001 — findings mapped to control requirements.
  • PCI DSS — scope-aligned testing for card-data environments.
  • Customer questionnaires — a report your prospects' security teams accept without a call.

Penetration testing FAQ

Straight answers to the questions we get before every scoping call.

How much does a penetration test cost?
A single web app or API test starts at $499. App plus API engagements start at $699, and custom network or AI scopes are quoted up to $999. The price is fixed in writing before we start.
How long does a penetration test take?
Web app and API tests typically run 5 to 10 business days. Network and AI scopes depend on size — you get a fixed timeline in the quote.
Do you test in staging or production?
Either. A staging environment is often better because we can be more aggressive, but production testing with agreed rules of engagement and test windows is fine too.
Which standards do you test against?
OWASP Top 10 and OWASP Testing Guide, OWASP API Security Top 10, OWASP LLM Top 10 and MITRE ATLAS for AI, plus NIST SP 800-115 and PTES for network scopes. Findings map cleanly to SOC 2, ISO 27001 and PCI DSS evidence requirements.

Thirty minutes on a call settles it. No sales script, no obligation.
