Hear it from our clients

What outcome accountability
looks like in practice. 

Theos operates across Singapore, Hong Kong, Malaysia, and the Philippines, serving regulated enterprises across the region. What our clients describe is a security partnership built on outcomes, trust, and continuity.

Theos built the engagement around the threat actors targeting our sector in Hong Kong. The findings were structured for HKMA submission and the gaps have since been closed.

The engagement identified gaps our existing programme had not surfaced. The findings went directly into our regulatory submission and the gaps have since been remediated.

Theos engaged credibly at board level and at SOC level in the same programme. The ability to do both simultaneously, and produce documentation that holds up to BNM examination, is what made the difference.

Common Questions

FAQs

Everything you need to know about THEOS and our cybersecurity services.

What makes THEOS Cyber different from other security providers?

Security is not a product you buy. It is an outcome you earn. Theos is built to protect APAC organisations against adversaries, operating within the regulatory frameworks governing financial institutions across Singapore, Hong Kong, Malaysia, and the Philippines.

Defence practitioners do defence. Offense specialists do offense. Response practitioners do response. Clients work with experts in their domain, accountable for outcomes in their field, supported by a dedicated Customer Success Manager from onboarding through the life of the engagement.

How does THEOS support regional APAC businesses?

Operating across APAC means navigating different regulators, different breach cultures, and different expectations of what security programmes should deliver. Theos is built for that complexity.

In Singapore, we align to MAS TRM and hold CSA certification. In Hong Kong, we work across HKMA iCAST, HKMA C-RAF, and GL20, where security decisions extend beyond compliance into cross-border data sensitivity and business continuity.

In Malaysia, we deliver against BNM RMiT and hold NACSA certification. In the Philippines, we hold DICT certification, working with BSP-regulated clients across a rapidly maturing security landscape.

Theos operates where our clients operate, accountable to the same frameworks that govern them.

What industries do you specialize in?

Theos works with organisations where the consequences of a breach are significant and the pressure to demonstrate security outcomes is real.

Our clients span financial services, fintech, insurance, gaming, logistics, maritime, manufacturing, technology, and non-profit organisations across the region.

What they share is real adversarial exposure and a need for a security partner who delivers outcomes they can act on.

Do you provide 24/7 monitoring?

Yes. Theos provides 24/7 managed threat detection and response across your environment. Our analysts are embedded in your monitoring programme and accountable for response times and outcomes. For clients on retainer, direct escalation access is available when it matters most.

What is your approach to compliance?

Theos helps clients meet regulatory requirements and deliver security outcomes that go beyond the audit.

We hold CREST accreditation and government-issued licences in Singapore, Malaysia, and the Philippines. Our practitioners work within MAS TRM, HKMA iCAST, BNM RMiT, and BSP frameworks daily. That knowledge shapes how we design programmes, what we test for.

What cybersecurity threats have you helped manage and handle?

Theos has responded to live breaches across our markets. That frontline experience feeds directly into how we build detection programmes and design adversary simulations.

Our response teams have handled ransomware, business email compromise, advanced persistent threats and insider threats. What we learn from each engagement compounds into the next.

What solution can you offer if I want end-to-end threat detection and response?

Theos delivers managed threat detection and response across your full environment: endpoint, identity, cloud, and network. Detection is calibrated to your critical assets, business context, and threat exposure. Our analysts monitor continuously, hunt proactively, and respond to confirmed threats.

For critical incidents, acknowledgement is within 15 minutes. Organisations that want to go further can engage our offensive security teams to validate whether their detection programme performs as expected.

What regions do you operate in?

THEOS operates across Singapore, Hong Kong, Malaysia, and the Philippines, with practitioners aligned to the regulatory frameworks governing each market. When a security incident crosses borders, your provider needs to move with it. Cross-border coordination is built into how we operate, not treated as an exception.

Why do APAC organisations choose THEOS?

APAC organisations choose Theos because we were built specifically for this region, operate within its regulatory frameworks, and stay accountable to the outcomes we commit to.

Our model is intelligence-driven, with findings from each engagement compounding into the next.
Every client works with a consistent senior team across every engagement. That continuity builds expertise and depth over time.

Security is not a product you buy. It is an outcome you earn.

How do I know if I need an MSSP or an in-house team? 

The answer depends on your risk profile and the maturity of your existing security function.

An in-house team gives you organisational context but takes time to build and requires continuous investment to maintain.

Theos gives you immediate access to practitioners across defence, offense, and response with 24/7 coverage. Some clients run a hybrid model, a lean internal function supported by Theos for monitoring, response, and specialist engagements.

Security is not a product you buy. It is an outcome you earn.
