Manual web, API, network, wireless and AI/LLM pentesting with auditor-ready reports and a free retest.
Every test is performed by a CREST CRT and CPSA certified tester who also holds OffSec OSCP, OSWA and OSWP. You work directly with the person doing the testing.
Prompt injection, jailbreaks, data leakage, and RAG and AI agent abuse, tested against the OWASP Top 10 for LLM Applications by an HTB Certified Offensive AI Expert (HTB COAE).
Penetration and segmentation testing that meets PCI DSS Requirement 11.4 and supports HIPAA risk analysis, with auditor-ready reports and a free retest.
Manual testing of web apps and REST and GraphQL APIs against the OWASP Top 10 and OWASP ASVS: authentication, access control, injection and business logic flaws.
External and internal network penetration testing, plus OSWP-certified Wi-Fi testing: WPA2/WPA3, enterprise wireless, rogue access points and guest isolation.
A clear scope and fixed price agreed up front, every finding manually validated, and a retest to confirm your fixes. Book a free scoping call to get started.
We agree the targets, testing window, rules of engagement and compliance goals (PCI DSS, HIPAA or SOC 2) up front, with a fixed price in writing before any testing begins.
A CREST CRT and OSCP certified tester attacks your web apps, APIs, networks, Wi-Fi or AI/LLM features by hand, chaining real attack paths and business logic flaws that automated scanners miss.
You get an auditor-ready report with proof-of-concept evidence, CVSS ratings and clear remediation steps, mapped to PCI DSS, HIPAA and SOC 2, plus a free retest once you've fixed the findings.
Testing is performed by a CREST CRT and OSCP certified tester, never handed off to a junior running a scanner. You work directly with the person doing the work.
Tools speed up coverage, but every finding is confirmed by hand. You get real, exploitable issues, not a scanner dump full of false positives.
Reports built to support PCI DSS, HIPAA, SOC 2 and ISO 27001, with the executive summary and evidence auditors expect to see.
Most engagements are scoped, tested and reported within one to two weeks, so testing never holds up a release or audit.
Scope, timeline and price are agreed in writing before work begins. No hourly surprises and no scope creep.
Once you fix the findings, a free retest confirms they are closed, so you can hand auditors and customers a clean result.
Targets, timing and contacts are agreed in a signed authorization and rules of engagement before testing starts. Work stays strictly inside the scope you set.
A non-destructive approach, with testing scheduled around your business hours and change freezes. Any high-risk action is agreed with you first.
Critical findings are reported to you immediately, not weeks later. Every action is logged and evidenced, so your compliance team can see exactly what was tested.
Book a free, no-obligation scoping call. We'll talk through your targets, timeline and compliance needs, and you'll get a clear fixed-price proposal.
