## FAQ

**What does A5 Cyber Nexus do?**
A5 Cyber Nexus is a cybersecurity and digital accessibility company based in Thanjavur, Tamil Nadu, India. We deliver WCAG 2.2 accessibility audits and VPAT/ACR reports, penetration testing (VAPT) and red teaming, AI/LLM security testing, managed security services, and compliance audits - including SEBI CSCRF, RBI, CERT-In, ISO 27001, ISO/IEC 42001 and the DPDP Act.

**Do you work with clients outside India?**
Yes. Engagements are delivered remotely to clients across the US, UK, EU, Canada, Australia, Singapore and the UAE, alongside India-specific work for SEBI-, RBI- and CERT-In-regulated organizations.

**Is AI security your main specialization?**
AI/LLM security testing - prompt injection, jailbreaks, agentic AI abuse and adversarial ML - is our lead offensive-security specialization, delivered alongside full-spectrum VAPT, red teaming, API, cloud and mobile security, plus ISO/IEC 42001 AI governance audits.

**What's the difference between an accessibility audit and a penetration test?**
An accessibility audit tests whether your product is usable by people with disabilities, measured against WCAG 2.2 and regulations like the RPwD Act and IS 17802. A penetration test (VAPT) tests whether an attacker can break in. We run both from one practice, since regulated organizations increasingly need both audited together.
