Tailored Security
for Modern Threats
Offensive expertise. Defensive strength. Strategic clarity. We bring all three to every engagement.
We attack systems.
We defend them.
We think strategically.
TSO was founded by security professionals who spent years on both sides of the fence, attacking systems and defending them. We saw too many organisations struggling with fragmented advice: one firm for pen testing, another for compliance, another for incident response. None of them talking to each other.
Offensive Expertise
We think like attackers because we have been attackers. Our offensive team finds the vulnerabilities that automated tools miss.
Defensive Strength
When threats emerge, we are ready. Our defensive capabilities are built on real-world experience containing and investigating breaches.
Strategic Clarity
Security without strategy is chaos. We help you build programmes that align protection with business objectives.
Three pillars.
One mission.
Offensive Security
Penetration Testing
Controlled attacks against your systems to identify exploitable vulnerabilities. We test what matters to your business, from external perimeter to internal networks, from customer-facing apps to cloud infrastructure.
Red Teaming
Full-scope adversary simulation that tests your entire security programme. Our red team operates like a real threat actor, combining technical exploitation, social engineering, and physical security testing.
Social Engineering
Your people are both your greatest asset and your largest attack surface. We test human vulnerabilities through realistic scenarios that measure how employees respond to manipulation attempts.
Vulnerability Research
When off-the-shelf testing is not enough, our researchers dig deeper. We analyse custom applications, proprietary protocols, and embedded systems to uncover zero-day vulnerabilities.
Defensive Security
Incident Response & Forensics
When a breach occurs, speed and expertise determine the outcome. Our incident response team contains threats, investigates root causes, and guides recovery while preserving evidence.
Threat Hunting
Automated detection catches known threats. Threat hunting finds the attacks that slip through. Our hunters proactively search your environment for signs of compromise that rules miss.
Managed Detection & Response
More than monitoring, less than a full in-house team. MDR combines technology, threat intelligence, and human expertise to detect and respond to threats across your environment.
Strategic Guidance
Security Programme Development
Whether you are building security from scratch or maturing an existing programme, we help you design a structure that fits your organisation. No generic templates.
Compliance Advisory
Compliance is the baseline, not the goal. We help you meet regulatory requirements efficiently while building security that actually protects your business.
Risk Assessments
You cannot protect everything equally. Risk assessments help you understand where your most significant exposures are and where to focus limited resources.
Policy & Procedure Development
Policies that sit on a shelf protect no one. We develop documentation that is practical, enforceable, and aligned to how your organisation actually operates.
