Red Teaming

Your security tools pass their audits. Your last penetration test came back clean. But would you notice a determined attacker inside your network today?

A SentryArk red team engagement answers that question. Our CRTO- and OSCE-certified operators emulate a real adversary — their tools, tactics, techniques and procedures (TTPs) — with an agreed objective, and test your organisation end to end: people, process and technology. You get the insight of a real attack, without the negative headlines.

Social engineering

Attackers often target people rather than systems. Where agreed in scope, we test how staff respond to phishing, pretext calls and physical access attempts, and turn the results into practical awareness improvements.

Detection and response gap analysis

Every technique we use is mapped to MITRE ATT&CK and compared against what your SOC, EDR and logging actually saw. The result is a clear list of detection gaps to close — and because SentryArk also runs managed SOC services, we can help you turn those findings into new detections.

Threat-led, objective-driven

Every engagement starts from objectives agreed with your leadership, such as reaching customer data, payment systems or domain admin. We profile the threat actors that target your sector and region, then build the campaign around their known techniques, with tooling and infrastructure built for your engagement rather than off-the-shelf payloads your EDR already recognises.

The scope is the whole organisation: your external perimeter, your people, physical access where approved, and the internal network once we are in.

Measuring detection and response

Stealth is part of the test. We record a timestamp for every action and compare it with what your SOC saw, and when. Where an action went undetected, we name the log source or detection rule that would have caught it.

Optional purple team sessions replay the attack chain with your blue team, so new detections can be built and verified on the spot instead of sitting in a report.

How an engagement runs

1. Planning and threat intelligence — objectives, rules of engagement and stop conditions agreed with your white team.
2. Reconnaissance — passive and active OSINT on your domains, staff, leaked credentials and exposed services.
3. Initial access — phishing, payload delivery, exposed services or physical entry where approved.
4. Lateral movement and objectives — privilege escalation through Active Directory and cloud identities towards the agreed objectives, while staying under your SOC’s radar.
5. Reporting and purple teaming — a full attack narrative with timestamps and detection gaps, then a replay with your defenders.

Safe by design

All activity runs under signed rules of engagement, with a named white team contact on your side and agreed stop conditions for any risk to production systems. Only a small group of your stakeholders knows the test is running, so the results reflect how your defenders respond to a real attack.

What we test

• Objective-based attack simulation agreed with leadership
• Social engineering — phishing, pretexting and physical access where in scope
• Initial access, lateral movement and privilege escalation
• Detection and response gap analysis against MITRE ATT&CK

What you receive

• Attack narrative with timeline
• Techniques used, mapped to MITRE ATT&CK
• What your defences detected, and what they missed
• Prioritised recommendations for people, process and technology
