Stop Guessing. Start Validating.
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:
Move beyond annual penetration tests and continuously assess your security posture. Re-test to confirm vulnerabilities are remediated and defences remain effective.
NodeZero identifies exploitable attack paths across cloud, on-premises, and hybrid environments, revealing how a real attacker could move through your organisation.
Security teams are overwhelmed with alert fatigue. Horizon3.ai helps organisations focus on genuine business risk, enabling faster decision-making.
Demonstrate measurable security improvements to boards, auditors, insurers, and regulators through validated testing and repeatable evidence of remediation.
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new vulnerabilities emerge, and by the time a penetration test report is reviewed, the picture may already be out of date.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.
Acora combines the power of Horizon3.ai’s NodeZero platform with offensive security expertise, security operations capabilities, and strategic cyber advisory services. Horizon3.ai reveals what attackers can exploit within their environment by identifying attack paths, validating security controls, and verifying remediation activities across cloud, on-premises, and hybrid estates. Together, customers gain far more than a testing platform. Our consultants work alongside internal teams to prioritise risk, accelerate remediation, strengthen operational security, and provide clear reporting to leadership teams, helping organisations continuously reduce risk and demonstrate cyber resilience.
Stop relying on assumptions and start understanding what attackers can really exploit.
