Leaders in Autonomous
Offensive Security

As Horizon3.ai’s 2025 UK & Ireland Partner of the Year, Acora helps organisations move beyond traditional penetration testing to continuous, real-world security validation. Together, we identify exploitable weaknesses, prioritise real risk, and verify remediation efforts are effective. Powered by Horizon3.ai’s NodeZero® Proactive Security Platform, organisations can continuously test their environments from an attacker’s perspective, uncovering exploitable attack paths before cyber criminals do. Acora complements this with the expertise, remediation guidance, and operational support needed to turn insight into action. Wherever you are on your autonomous offensive security journey, Acora and Horizon3.ai can help:

Prove risk reduction

Prove Risk Reduction.

Demonstrate measurable security improvements to boards, auditors, insurers, and regulators through validated testing and repeatable evidence of remediation.

The Risk You Can’t See Can Still Hurt You

Business leaders are under growing pressure to prove cyber resilience. Boards want assurance, regulators demand evidence, and insurers expect proof of effective controls. Yet many organisations still rely on annual assessments that offer only a snapshot of risk. The challenge is that threats evolve faster than traditional testing cycles. Environments change constantly, new vulnerabilities emerge, and by the time a penetration test report is reviewed, the picture may already be out of date.

Security teams don’t need more findings. They need to understand which weaknesses attackers can exploit and where to focus remediation efforts. NodeZero changes the game by continuously validating your environment, uncovering real attack paths and providing clear evidence of genuine exposure.

From Attack Path to Action Plan:
