Built for adversaries who know this region.

Security is not a product you buy. It is an outcome you earn. THEOS is built for one thing: protecting APAC organisations against adversaries. Every engagement is a security engagement. Every outcome is a security outcome. We are an APAC firm, built here, operating here, with practitioners who have worked inside the regulatory frameworks governing financial institutions across Singapore, Hong Kong, Malaysia, and the Philippines continuously. What sets us apart is how we deliver. Our model is intelligence-driven. Findings from each engagement compound into the next, so each cycle builds on the last. Defence practitioners do defence. Offense specialists do offense. Response practitioners do response. Clients work with experts in their domain, experts in their field. Every client works with a dedicated Customer Success Manager who owns delivery from onboarding through the life of the engagement, ensuring commitments are met and escalations are handled directly.

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, working with organisations where security governance is tied to enterprise risk management and board-level accountability. In Hong Kong, we work across HKMA iCAST, HKMA C-RAF, and GL20, in a market where security decisions increasingly extend beyond compliance into cross-border data sensitivity and business continuity. In Malaysia, we deliver against BNM RMiT and the Cyber Security Act 2024 and hold NACSA certification, helping organisations translate security outcomes into business risk language that boards can act on. In the Philippines, we hold DICT certification and work with organisations across a rapidly maturing security landscape, including BSP-regulated clients where programme gaps carry real regulatory and reputational consequences. THEOS operates where our clients operate, accountable to the same frameworks that govern them.

THEOS works with organisations where the cost of a breach is highest and the pressure to demonstrate security outcomes is real. Our clients span banking and financial services, fintech, crypto, insurance, gaming, hospitality, logistics, maritime and shipping, manufacturing, healthcare, energy, airlines, real estate, technology, and non-profit organisations. What they share is real adversarial exposure and a need for a security partner who delivers outcomes they can act on.

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 means that when something critical happens, you reach a decision-maker immediately.

THEOS helps clients meet regulatory requirements and deliver security outcomes that hold up beyond the audit. Compliance is the floor, not the ceiling. We hold the certifications that matter in our markets: CREST accreditation, CSA in Singapore, NACSA in Malaysia, and DICT in the Philippines. Our practitioners understand the frameworks governing each: MAS TRM in Singapore, HKMA iCAST, HKMA C-RAF, and GL20 in Hong Kong, BNM RMiT and the Cyber Security Act 2024 in Malaysia, and the Critical Infrastructures Ordinance in Hong Kong. In the Philippines, we support BSP-regulated clients navigating an increasingly demanding compliance environment. That knowledge shapes how we design programmes and what we test for. When findings go to regulators and boards, they hold up.

THEOS has responded to live breaches across our markets and industries. That frontline experience feeds directly into how we build detection programmes, structure retainers, and design adversary simulations, giving clients the advantage of what we have seen in the field. Our response teams have handled ransomware, business email compromise, advanced persistent threats, insider threats, and supply chain compromises. What we learn from each engagement compounds into the next.

THEOS delivers managed threat detection and response across your full environment: endpoint, identity, cloud, and network. Our analysts monitor continuously, hunt proactively, and respond to confirmed threats. We map detection to your environment, incorporating your critical assets, business context, and threat exposure, and tune it continuously as we learn more about how you operate. For critical incidents, response is initiated within a 15-minute SLA. For organisations that want to go further, our offensive security teams can test whether your detection capabilities catch what they should. Each engagement builds on the last, compounding intelligence across every cycle.

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.

Because security outcomes in this region are not delivered by global firms who parachute in, or local providers who lack the depth to handle what they find. APAC organisations choose THEOS because we were built specifically for this region, operate inside its regulatory frameworks, and stay accountable to the outcomes we commit to. Our model is intelligence-driven. Findings from each engagement compound into the next, so every cycle builds on the last. 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. Every client works with a consistent senior team across every engagement. For organisations managing security across multiple markets and regulatory regimes, that continuity has compounding value. Global providers cannot offer it. Their model requires rotation. Security is not a product you buy. It is an outcome you earn.

The answer depends on your risk profile, budget, and the maturity of your existing security function. An in-house team gives you deep organisational context but takes time to build, is difficult to staff with specialist talent, and requires continuous investment to maintain. THEOS gives you immediate access to practitioners across defence, offense, and response, with 24/7 coverage built around the regulatory and threat environment of our markets. Many of our clients run a hybrid model, a lean internal function supported by THEOS for monitoring, response, and specialist engagements.
