Questions we hear often
What is included in a fractional vCISO engagement?
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.
What determines the scope of a penetration test?
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.
What is AI/LLM security testing?
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.
