Cybersecurity for
operational technology
and critical infrastructure
We help operators of essential infrastructure find cybersecurity weaknesses before attackers can exploit them, and recommend how to address them. A founder-led specialist firm based in Abu Dhabi, working across the UAE and wider GCC on systems where a security failure can have physical consequences.
Who We Are
Specialists in the
operational attack
surface
OscarTango is a specialist cybersecurity firm focused on operational technology, critical infrastructure and adversarial security. Complex operational environments require practitioners who understand both how systems are designed to operate and how adversaries attempt to compromise them. We work at that intersection — industrial and control systems, the networks and software that connect to them, and the safety-critical processes that depend on them.
More about OscarTangoCapabilities
Services
Six capability areas, built around the realities of operational environments — where availability is paramount and the consequences can extend well beyond data.

Independent Assurance
External validation,
before it matters
Specialist external validation gives organisations independent confidence that cybersecurity controls, architectures and critical projects perform as intended — before weaknesses become operational problems.
Where it fits
- Major projects and critical-infrastructure investments — design assurance, factory and site acceptance testing, and pre-go-live validation for new plant, networks and control systems.
- Transformation programmes — an independent technical view at the stage gates where sponsors decide whether to proceed.
- Third-party and vendor assurance — review of integrator, vendor and service-provider work against what was specified and contracted.
- Independent review for executives and boards — an external view of cyber risk and control effectiveness, for the people accountable for it.
Independent of Delivery
We do not build, integrate or operate the systems we assess, and we are not a reseller for anyone else's products. Our conclusions answer to the evidence.
Assurance at the Right Gate
Design review, factory and site acceptance testing, pre-go-live validation and post-implementation review — assurance applied at the stage where findings are still inexpensive to act on.
Evidence, Not Assertion
Conclusions are grounded in hands-on testing and technical review, expressed in terms boards, regulators and engineering teams can each act on.
