Security controls need to be tested to be trusted. Theos tells you whether yours work against the adversaries targeting your environment. 

Theos Cyber delivers CREST-certified vulnerability assessment and penetration testing that tells you
whether your controls work, not whether they are configured.

THE CHALLENGE

Why untested controls fail at the wrong moment.

Zero-day exploitation increased 42% year-over-year in 2025. Newly disclosed vulnerabilities are being weaponised within days of public release. Organisations that are not testing their controls against current vulnerability data are operating with a picture that is already out of date.

Most organisations have security controls in place. Fewer know whether those controls would stop an adversary who is actively trying to circumvent them. Configuration is not the same as effectiveness. A firewall rule that passes a compliance audit may still permit the lateral movement path an attacker would use.

Regulatory frameworks across APAC (including MAS TRM and HKMA iCAST) carry requirements for regular security testing, including threat-led penetration testing for certain institutions. The testing obligation exists because assumed security is not sufficient.

HOW THEOS ADDRESSES IT

What Theos delivers.

Vulnerability Assessment and Penetration Testing

CREST-certified testing across applications, network infrastructure, cloud environments, and APIs. Theos practitioners test against the vulnerability classes and exploitation techniques adversaries are currently using, not just known CVEs. Findings are documented to the standard regulated institutions require, with remediation priority mapped to actual exploitation risk.

Vulnerability Assessment and Penetration Testing
Vulnerability Management

A continuous programme that identifies, prioritises, and tracks remediation across your environment. Vulnerability Management turns periodic testing into an ongoing capability, ensuring that new exposures are identified and addressed before adversaries find them. Findings from VAPT engagements feed directly into the programme.
