"My experience with ComplexTech has exceeded my own expectations. As a client, I've found the company to be highly reliable and very credible. Their service is fast and friendly and all my questions were always answered in a prompt and timely manner."
J. Lim
Business Owner
"ComplexTech ran our annual external and internal pen test and didn't just hand us a scanner printout with a logo slapped on it. They chained together a few low-severity findings into something that actually would have gotten an attacker into our sensitive systems, and walked our engineering team through exactly how. The report was usable and findings were prioritized by real business risk, not just CVSS score."
IT Director
"We brought ComplexTech in to review a core piece of our platform before a big client's security audit. Their engineers caught an authorization flaw in our API layer that three prior code reviews missed, and explained it in a way our dev team could actually fix in a sprint instead of a quarter. Worth every dollar going into that audit with confidence."
IT Manager
"Before ComplexTech, security was something we reacted to. Now we have an actual roadmap, board-ready reporting, and someone who can speak to our cyber insurance underwriter and our engineering team in the same afternoon. Getting that level of leadership without a six-figure full-time hire made this a no-brainer for a company our size."
B. Carmello
Head of IT, UASC
"ComplexTech helped us stand up an actual application security testing program instead of just running a scan before releases. They integrated testing into our SDLC, trained our developers on the findings instead of just filing tickets, and our defect rate on security issues has dropped noticeably since."

Fortune 250 Company
A fractional vCISO engagement typically includes security strategy and roadmap development, board and executive reporting, policy and procedure creation, vendor and third-party risk management, incident response planning, and security budget and tooling guidance. ComplexTech tailors scope to your size and maturity with monthly or quarterly engagement models so you get executive-level leadership without a full-time hire.
Penetration test scope depends on your assets, testing goals, and risk profile — for example external vs internal networks, web applications, wireless, social engineering, and whether retesting is included. ComplexTech does not publish fixed pricing because every engagement is scoped individually. After a consultation, you receive a transparent proposal that defines coverage, timeline, and deliverables before work begins.
AI/LLM security testing evaluates risks specific to large language model applications, including prompt injection, jailbreaks, insecure output handling, training-data poisoning, and model abuse paths. ComplexTech applies OWASP LLM Top 10 expertise to test how your AI features behave under adversarial input and whether controls protect sensitive data and downstream systems.
