Prove your defenses hold to DORA, NYDFS, and the SEC, continuously, not once a year.
SIEGE runs as a persistent adversary against your environment, emulating the financially-motivated and nation-state actors that target banks, insurers, and capital markets. It produces the dated, repeatable evidence DORA Threat-Led Penetration Testing, NYDFS 23 NYCRR 500, and SEC 10-K Item 106(b) disclosure require, mapped to MITRE ATT&CK and ranked by real exploitability.
This is how the breach actually happens.
Who's actually coming for you.
The actors targeting financial institutions are among the most capable and best-resourced in the world. SIEGE emulates how they actually operate, as documented in CISA and FS-ISAC reporting.
Every framework asks the same question. SIEGE answers it once.
Each mandate below asks, in its own language, whether you can prove your defenses work. SIEGE produces the evidence one time and maps the result to each framework your examiners use.
| Mandate | Requirement | SIEGE Evidence |
|---|---|---|
| DORA Art. 26 | Threat-Led Penetration Testing (TLPT) | Intelligence-led adversary emulation with dated, repeatable reports |
| DORA Art. 24–25 | Digital operational resilience testing | Continuous control-validation evidence |
| NYDFS 500.05 | Penetration testing & vulnerability assessment | Annual plus continuous adversarial validation |
| SEC 10-K Item 106(b) | Risk management & strategy disclosure | Year-round material-risk evidence, not a snapshot |
| PCI DSS 4.0 Req 11.4 | Segmentation & penetration testing | Proven exploit paths and segmentation validation |
Built under DARPA. Validated by DoD.
When SIEGE confirms your defenses hold, that finding carries the weight of the DARPA CASTLE program and operational validation across DoD and U.S. Government environments. For your board, your examiners, and your customers, it is the most credible statement of resilience a financial institution can present, proof, not posture.
The cost of finding out the hard way.
