Learn moreAd-hoc Research
Reverse engineering, fuzzing, exploit development, and offensive innovation across IoT, defense, and automotive sectors. CVE generation and responsible disclosure.
Learn moreRegulatory Compliance
The Regulations Driving Offensive Testing
European regulation now mandates adversarial security testing. Non-compliance carries severe penalties — and the deadlines are already here.
160,000+ Entities Affected
The NIS2 Directive requires essential and important entities to conduct regular security testing, including penetration testing and red team exercises. Penalties up to 10M EUR or 2% of global revenue.
SilentForce delivers NIS2-aligned penetration testing and adversarial simulation for energy, healthcare, and telecommunications sectors.
Financial Sector Mandate
DORA requires financial entities to conduct Threat-Led Penetration Testing (TLPT) under the TIBER-EU framework every 3 years. In effect since January 2025.
SilentForce has extensive TIBER-EU experience with banking and financial services clients across Spain.
AI Systems Under Scrutiny
Mandatory adversarial testing for high-risk AI systems. Deadline: August 2026. Penalties up to 35M EUR or 7% of global revenue — the strictest in EU regulatory history.
SilentForce is the first Spanish firm with dedicated AI Red Teaming capability, including proprietary AI-CVSS scoring.
