01

Threat Intelligence

The adversaries targeting your sector, named and mapped.

FourCore tracks the actors, campaigns, and TTPs hitting your industry and region, then maps them to the attack paths your environment would actually face. Your team stops testing generic checklists and starts preparing for the threat that is already out there.

02

Hunt

Turn intelligence into a testable hypothesis.

Which tactics would this actor use against you, in what order, and which control should catch them first? The hunt defines exactly what will be proven, so the exercise answers a question leadership actually asked.

Explore capability

03

Emulate

Their playbook, executed against your defenses.

The actor's kill chain runs as controlled, authentic behavior across endpoint, identity, network, and cloud. Not a scanner. Not a checklist. The same procedures the adversary would use, in the same order, in production-safe scope.

Explore capability

04

Validate

Every control response, measured against reality.

Each emulated step is correlated with telemetry, alert timing, and control outcomes across your stack. A red cell is not a score or an estimate — it is an observed miss, with the evidence attached.

Explore capability

05

Improve

Misses become detections your team ships the same day.

Every gap arrives with Sigma, YARA, and Snort content built from the observed behavior, ready for your SIEM and EDR. Remediation is not a report recommendation — it is working detection logic for the exact attack that beat you.

Explore capability

06

Repeat

Proof the fix held, on a schedule you can report.

The same adversary behavior becomes a standing regression check. Each cycle tightens coverage and produces the trend line leadership asks for: are we actually getting harder to breach, and can you prove it?

Frequently Asked Questions

Everything you need to know about FourCore ATTACK, security control validation, and continuous validation in regulated environments.

FourCore ATTACK is an Adversarial Exposure Validation (AEV) platform that continuously and safely simulates real-world cyberattacks against your environment to validate whether your security controls actually work. It combines breach and attack simulation with continuous automated red teaming, maps every test to MITRE ATT&CK, and gives security teams empirical evidence of exploitable gaps plus prioritized, audit-ready remediation guidance.

A penetration test is a point-in-time, mostly manual assessment performed once or a few times a year. FourCore ATTACK runs continuously and automatically, validating your controls 24/7 as your environment and threats change. Pen testing finds vulnerabilities at a moment in time; FourCore proves, on an ongoing basis, whether your defenses stop today's attacks — and re-validates automatically after you remediate.

Yes. FourCore ATTACK is designed to run safely in production. Its simulations emulate adversary behavior using controlled, non-destructive actions — validating whether controls detect and block techniques without deploying real malware, damaging systems, or disrupting operations. Tests are scoped and reversible, so teams get production-accurate evidence of control effectiveness without the risk of an uncontrolled live attack.

Yes. FourCore ATTACK integrates with major EDR, XDR, and SIEM platforms — including CrowdStrike, SentinelOne, Palo Alto Cortex XDR, Microsoft Sentinel, IBM QRadar, and Google SecOps — so validation results map directly to the alerts (or missing alerts) in your tools. This lets you measure real detection coverage, tune rules, and prove the ROI of the security stack you already own.

Security controls should be validated continuously, not once or twice a year. Environments, configurations, and threats change constantly, so a control that worked last quarter may silently fail today. Continuous validation — running automatically and re-testing after every change or remediation — is why Gartner ties continuous exposure management to a measurably lower likelihood of breach versus periodic testing.

FourCore ATTACK helps regulated entities meet SEBI's Cyber Security and Cyber Resilience Framework (CSCRF) by continuously validating security controls and auto-generating audit-ready evidence. CSCRF expects organizations to test and demonstrate control effectiveness; FourCore supplies the empirical proof — what was tested, what was blocked, and what was remediated — mapped to the framework's requirements and structured for clean auditor handoff.
