FourCore ATTACK

FourCore ATTACK is an adversarial exposure validation platform for security teams that need recurring, controlled simulations rather than occasional point-in-time assessments. It suits SecOps and detection engineering teams responsible for proving that endpoint, email, network and analytics controls respond to realistic behavior. Its strongest case is the closed loop from attack emulation to ATT&CK-mapped evidence, remediation changes and retesting; teams wanting transparent package pricing should look elsewhere.

Overview

FourCore ATTACK continuously models real-world cyberattacks to validate security controls. Its agentic threat intelligence connects current threats with an organization’s environment, helping teams prioritize which tests to run. Campaigns emulate adversary tactics, techniques, procedures, indicators and artifacts in controlled conditions, while lightweight Windows and Linux agents connect to the SaaS platform.

Results correlate simulation steps with telemetry, alert timing, control responses and outcomes across security tools. Each behavior maps to MITRE ATT&CK and is classified as detected, partially detected, blocked or missed. That makes the product more useful for measuring defensive coverage than a simple pass/fail scanner. FourCore says simulations are designed not to disrupt or destroy target systems, an important safeguard when testing production-connected controls.

Key features

• Broad control coverage: campaigns address endpoints, email, WAFs, network segmentation, SIEM, EDR, XDR, firewalls, DLP and exfiltration controls, allowing one program to examine several defensive layers.
• Actionable evidence: linking behavior to telemetry, alert timing and ATT&CK techniques helps detection engineers identify where a control failed and what to change next.
• Detection refinement: FourCore can generate or refine Sigma, YARA and Snort rules, plus configuration changes, then retest the behavior. This shortens the path from finding to verification, although teams still need ownership of rule review and deployment.
• Continuous scheduling: recurring simulations support ongoing assurance as threats and configurations change, rather than a single annual snapshot.
• Workflow and tool integrations: findings can move into Jira and ServiceNow. Named integrations include CrowdStrike, SentinelOne, Microsoft Sentinel, QRadar, Trend Micro Vision One, Proofpoint, Cisco Secure Email, Cortex XDR, ServiceNow, Microsoft Defender for Endpoint, Harfanglab, Qualys Cloud EDR, LimaCharlie and ZScaler NSS.
• Security safeguards: FourCore states that UI and API traffic uses HTTPS/TLS 1.2 or higher, with customer-selectable two-factor enforcement or SSO. It reports ISO 27001:2022 certification, CSA STAR Level 1 and detailed third-party penetration tests at least annually.

Pricing

FourCore ATTACK uses paid, custom pricing. Maker pages direct prospective customers to book a demo, so there are no published plans, seat counts, quotas, trial duration or renewal terms to compare. This fits organizations prepared for a security-platform buying process, but makes budget qualification harder for smaller teams and prevents a clear price-to-coverage comparison before contacting FourCore.

Platforms

The deployment model is hybrid. FourCore describes an AWS-hosted SaaS platform and invites customers to discuss on-premises solutions. Lightweight agents support Windows and Linux; the Windows agent is supplied as a preconfigured MSI and installed as a service. The listed platform coverage is Linux, Windows, web and self-hosted, with agent-based attack simulation.

Who it's for

Choose it for SecOps, detection engineering and control-assurance teams that need scheduled adversary emulation across multiple security products, defensible ATT&CK coverage metrics and a remediation-to-retest workflow. It is particularly suitable where Jira or ServiceNow processes and existing endpoint, SIEM, email and network tooling can consume correlated findings.

It is a weaker fit for a team seeking a free, self-directed test library, a simple open-source lab, or an immediately purchasable package with public limits. Organizations requiring on-premises deployment should confirm that arrangement directly with FourCore.

Pros and cons

Pros

• Closed-loop validation: generated rules and configuration changes can be retested, tying remediation to measurable behavior.
• Useful evidence model: ATT&CK mapping and detected/partially detected/blocked/missed outcomes give security leaders a consistent language for control gaps.
• Wide integration footprint: support for major EDR, XDR, SIEM, email and workflow products can reduce manual evidence collection.
• Safety and assurance controls: non-destructive simulations, TLS, 2FA or SSO options, ISO 27001:2022 and annual external penetration testing address operational and governance concerns.

Cons

• Custom pricing only: buyers cannot assess cost, seats or usage limits without entering a sales process.
• SaaS is the stated default: teams needing an on-premises installation must establish availability and terms with FourCore.
• Operational ownership remains with the customer: generated detections and configuration changes still require review, rollout and monitoring in the organization’s tools.

Verdict

FourCore ATTACK is a strong choice for security teams that need recurring adversary simulations tied to control responses, ATT&CK coverage and retestable detection improvements. Its breadth, integrations and evidence model support mature SecOps programs. Look elsewhere if you require public pricing, a free starting tier or a clearly defined on-premises package before engaging a vendor.
