Know if your defences actually work.
A Breach & Attack Simulation (BAS) safely emulates real-world adversary techniques against your environment, answering the question every security investment leaves open: would we actually catch this? Delivered by SBL Cybermonitoring.
Security tools configured ≠ defences working.
You've invested in EDR, SIEM, email security, identity protection, and an MDR service. But those investments only matter if they actually detect and block real attacks. Not in theory, but in practice. Most organisations discover during an incident that a tool was misconfigured, a rule never fired, or an alert never reached anyone. BAS turns that assumption into evidence.
Real attacks, safely executed.
The simulation runs realistic attacker behaviour against your environment — execution, persistence, privilege escalation, lateral movement, exfiltration — and measures, step by step, what your defensive stack saw, blocked, or missed.
Define the engagement
We agree on the scope: which environments are in play, which MITRE ATT&CK techniques to simulate, and what your priority concerns are: ransomware, insider threat, credential theft, data exfiltration.
Adversary emulation
Nemesis executes the agreed attack scenarios safely against your environment. Every action is controlled, reversible, and logged. Designed to test defences without putting production at risk.
Findings & remediation
You receive a detailed report mapping every step of the attack chain to what your defences detected, blocked, or missed. With prioritised remediation guidance to close the gaps.
Advanced Attack Simulation Platform.
The simulation engine behind the engagement. This purpose-built adversary emulation platform is designed for safe, controlled and repeatable attack simulation aligned to the MITRE ATT&CK framework.
Production-safe attack simulation.
The platform executes real attacker behaviour (not synthetic test traffic) across the full kill chain. Each technique is wrapped in safety controls: nothing is destructive, nothing is irreversible, and every action is auditable.
Aligned to MITRE ATT&CK, continuously updated with the latest threat actor TTPs, and operated by SBL Cybermonitoring's offensive security team.
Test against the attacks that matter.
Choose from a library of pre-built scenarios or build a custom engagement around your specific concerns. Every scenario is mapped to MITRE ATT&CK and reflects current real-world threat actor behaviour.
Ransomware kill chain
Initial access via phishing → execution → persistence → privilege escalation → lateral movement → file encryption simulation. Validates the end-to-end ransomware detection and response capability of your stack.
Credential theft & abuse
Credential dumping, Kerberoasting, pass-the-hash, token impersonation. Tests whether identity-layer attacks trigger detections in your EDR, SIEM, and identity protection tooling.
Endpoint defence validation
Direct testing of your EDR's behavioural detection: process injection, defence evasion, living-off-the-land binaries. Shows precisely which techniques bypass your endpoint controls.
Data exfiltration
Staging, compression, encryption, and exfiltration over multiple channels — DNS, HTTPS, cloud storage. Validates DLP, egress controls, and SOC visibility on data leaving the environment.
Cloud & identity attacks
OAuth abuse, consent phishing, conditional access bypass, session hijacking. Tests cloud-native attack paths that traditional endpoint tools cannot see.
Custom adversary emulation
Want to simulate a specific threat actor relevant to your sector — FIN7, APT29, ransomware groups? We build the engagement around their known TTPs and your environment.
Executive-ready, engineer-actionable.
You receive a comprehensive report that shows exactly what your defences saw, what they missed, and what to fix — with remediation guidance built in.
Executive summary
A board-ready overview of your defensive posture against the simulated threats.
Attack chain breakdown
Step-by-step replay of each scenario with detection and prevention outcomes.
MITRE ATT&CK mapping
Every technique tested mapped to MITRE ATT&CK, with detection coverage scoring.
Detection gap analysis
Specific gaps in EDR, SIEM, email security, and identity tooling with severity ratings.
Remediation guidance
Practical recommendations included in the report: tuning advice, missing rules, suggested controls. Your team can act on it directly.
Tool effectiveness scoring
Per-tool effectiveness across the attack chain, independent validation of your security stack ROI.

Vendors have an interest in their product looking good. SBL Cybermonitoring is independent: we don't sell EDR, we don't resell SIEM, and we have no commercial reason to favour one tool over another.
We tell you, with evidence, what your stack catches and what it doesn't. Then we hand you a remediation plan you can act on. Internally or with your existing partners.

Practical questions, practical answers.
How is this different from a penetration test?
A pen test asks "can a skilled attacker get in if they try?" — usually goal-oriented and creative. BAS asks "do your existing controls detect and stop the techniques attackers actually use day-to-day?" — broad, repeatable, and mapped to the full attack chain. Pen testing tests your perimeter; BAS tests your defensive stack.
Is it safe to run in production?
Yes. Nemesis is designed for production environments — every technique uses safe, controlled execution with no destructive payloads. We can also run in dev/staging environments if preferred. The scope is agreed up-front; nothing happens outside it.
Will the SOC know it's a simulation?
Your choice. We can run "black box" (your SOC doesn't know, which gives the most realistic detection picture) or "white box" (your SOC is informed, which is useful for tuning and tabletop exercises). Most organisations start black box, then iterate.
Does the report include remediation?
Yes. The report includes specific remediation guidance for every detection gap found — tuning recommendations, missing rules, suggested controls, and prioritisation. Your team can act on it directly, or use it as input to a separate hardening engagement. Request a sample report »
How does this support compliance?
BAS is increasingly expected by NIS2, DORA, ISO 27001 (Annex A.5.7 threat intelligence, A.8.7 protection against malware), and PCI DSS 4.0. The deliverable provides documented evidence that your security controls have been independently tested against current threats.
