Forenzy Siege
Prove your defenses stop real attacks — continuously
Forenzy Siege is a breach and attack simulation (BAS) platform that continuously and safely launches real-world attack techniques against your environment — mapped to the MITRE ATT&CK framework — to show what your defenses actually detect and block. Instead of assuming your EDR, SIEM, firewall and email gateway are doing their job, you get evidence: which attacks were stopped, which were only detected, and which walked straight through, with every gap tied to a fix.
Siege complements annual pentests and red teams with continuous MITRE ATT&CK validation; pair with Forenzy Prism to track remediation when simulations expose gaps.
Your stack
How BAS fits with pentesting and purple team
- BAS runs continuously; pentests are point-in-time, human-led depth — the two complement each other.
- Validates EDR, SIEM, email and network controls with evidence, not assumptions.
- Forenzy red and purple team services feed Siege with current adversary TTPs.
- Safe production emulation — exercises detections without disrupting live systems.
- Forenzy Prism tracks fixes when simulations surface detection or blocking gaps.
The problem
You bought the tools. Do they actually work?
Security stacks get configured once and trusted forever. Rules drift, agents fail quietly, exceptions pile up — and most teams discover a broken control during a real breach, the worst possible moment to find out a detection never fired.
Continuous attack simulation
Safely launch real attack techniques on a schedule, not once a year.
MITRE ATT&CK coverage
Test against the full library of adversary tactics and techniques.
Multi-vector attacks
Exercise email, endpoint, network and cloud, end to end.
Control validation
Prove whether your EDR, SIEM, firewall and email gateway detect and block.
Detection-gap analysis
See exactly where an attack slipped through unseen.
Emerging-threat emulation
New, freshly disclosed exploit techniques added as they appear.

Why Forenzy
Loaded with what we use in real red team ops.
The same offensive team that runs your red team engagements feeds Siege with current TTPs and emerging exploits — so you're tested against what attackers actually use today, not a stale canned library.
Integrations
Validate the controls you already run.
Siege exercises detections across your stack and pushes validation results into the tools your SOC and engineering teams use.

Use cases
Where teams deploy it first
SOC detection tuning
Prove which MITRE techniques your SIEM rules actually catch — and which only generate noise.
EDR validation
Safely emulate ransomware, lateral movement and credential theft against production agents.
Board-ready metrics
Show control coverage and improvement trends mapped to ATT&CK — not vanity scan scores.
Proof in practice
Customer outcomes
Healthcare
SOC closed three silent detection gaps in 30 days
Challenge: Annual pentest passed, but purple team found the EDR did not block several common techniques.
Outcome: Siege continuous simulations surfaced gaps in email and endpoint layers; playbooks and rules updated with measurable coverage lift.
Manufacturing
Email gateway bypass caught before phishing campaign
Challenge: Security assumed MIMEcast blocked malicious attachments; BAS proved otherwise for a specific file type.
Outcome: Policy fix and re-test confirmed block rate — validated with Siege before the next audit.
Continuous BAS validation surfaces detection gaps before real attackers do — the same control failures our red team engagements exploit on day one, now tested on a schedule.
FAQ
Common questions
What is breach and attack simulation?
BAS continuously and safely simulates real attacks against your environment to validate whether your security controls actually detect and stop them.
How is BAS different from a penetration test?
A pentest is a point-in-time, human-led assessment. BAS runs continuously and automatically, validating your controls against a broad, constantly updated attack library over time. The two complement each other.
Is it safe to run in production?
Yes — Siege uses controlled emulation designed to exercise your defenses without disrupting or damaging live systems.
Does Siege replace purple team exercises?
No. Siege automates continuous control validation mapped to MITRE ATT&CK. Forenzy purple team services add human-led collaboration between offensive and defensive teams — the two strengthen each other.
Which security controls does Forenzy Siege validate?
Siege exercises EDR/XDR, SIEM detections, email security gateways, firewalls and cloud-native controls — showing which attacks were blocked, detected only, or missed entirely.
