Active Cyber Defence

Why it matters

Cyber threats are faster, more targeted, and increasingly external.

Attackers exploit exposed assets, credentials, and supply chains long before alerts are raised. In high-risk sectors such as government, financial services, and critical infrastructure, the impact is immediate and material.

Many organisations still rely on reactive detection, leaving a gap between exposure and response. During that time, attackers gain access, move laterally, and increase the scale of impact.

Active Cyber Defence closes that gap. It focuses on identifying external risk, disrupting attack paths, and reducing exposure before compromise occurs. The outcome is faster containment, reduced attacker opportunity, and demonstrable risk reduction in environments where resilience and assurance are critical.

Speed transforms cyber defence from reactive damage control into proactive risk elimination. When threats are contained in half a minute rather than hours, attack impact collapses. Early containment is the difference between a minor incident and a business-damaging breach.

of incidents closed with automation and AI. Intelligence amplification removes alert noise before analyst time is consumed. This means your team focuses on genuine threats requiring human judgement, not on filtering false positives. It’s the efficiency multiplier that makes 24/7 defence sustainable at any scale.

Key features

Dark Web Monitoring

Continuously scan the dark web for exposed credentials, brand impersonation and emerging threat activity. Leaked data is detected, identified, and verified – enabling proactive defence against indicators of compromise. This provides reduces overall risk of account takeover, brand damage, and breaches.

Attack Path Analysis

Analyse relationships between vulnerabilities, identities, and assets to identify viable attack paths within your environment. Risks are prioritised based on how attackers can move towards critical systems. This provides focused remediation, reduced lateral movement risk, and prevention of high-impact compromise.

External Attack Surface Management

Continuously map and monitor internet-facing assets to identify unknown, unmanaged, and exposed services. Risks are discovered, validated, and prioritised based on real-world exploitability. This provides improved visibility, reduced external attack surface, and proactive mitigation of exposures before they can be exploited.

Automated Defensive Actions

The SCC Pulse automation platform applies automated, intelligence-driven controls to proactively disrupt threats before they escalate. Signals are continuously assessed, actions orchestrated, and defensive response is executed in real time. This provides reduced attacker dwell time, consistent disruption of malicious activity, and a more proactive, resilient security posture.

How it works

Step 1

Comprehensive visibility across your entire estate

We establish connectivity across endpoints, identity systems, cloud applications, on-premises infrastructure and networks. We map your attack surface, identify coverage gaps and establish a security baseline unique to your organisation’s risk profile. Complete visibility is the prerequisite for everything that follows

Step 2

Continuous proactive threat hunting

Our Threat Analysts hunt through billions of signals daily using certified threat intelligence. They don’t wait for alerts. They actively search for compromise indicators, unusual patterns and emerging attack techniques. Proactive hunting means threats are discovered and tracked before they progress through attack chains.

Step 3

AI-driven filtering and intelligence amplification

SCC Pulse processes raw signals, adds context, enriches data and triages alerts before analysts see them. Noise is removed. False positives are eliminated. The platform learns continuously. This amplification means analyst time is spent on genuine threats, not alert fatigue. Speed and precision increase simultaneously.

Step 4

Instant containment with guided response

When a genuine threat is confirmed, containment begins within seconds. Our analysts provide immediate investigation, containment actions and guided remediation. We work with your team to understand scope, isolate affected systems and limit damage. Rapid response means business impact is minimised and recovery is faster.

Step 5

Continuous improvement through performance analysis

We conduct regular reviews of your threat landscape, detection performance and security posture. We analyse trends in the attacks targeting you, refine detection rules, recommend control improvements and evolve response playbooks. Your defences strengthen as threats evolve. This is security that learns.

FAQs

How is the ACDC different from a traditional SOC or SIEM?

Traditional cyber security focusses primarily on internal security posture and reactive mitigation. Active Cyber Defence (ACD) actively hunts for exposed risks and potential attacks. ACD combines threat intelligence, external visibility, and automated action to identify, prioritise, and reduce risks before they can be exploited.

Where traditional approaches rely on tools to surface alerts, ACD operates as a continuous, intelligence-led model: integrating people, process, and platforms (such as SCC Pulse) to deliver rapid decision making and defensive action.

What does “intelligence amplification” mean in practice?

SCC Pulse processes billions of security signals daily. It filters out noise, adds context, enriches data, and presents only the threats that require analyst attention. This means analysts aren’t drowning in false positives. They’re focused on genuine risks. The platform learns continuously. Over time, it becomes more accurate at distinguishing signal from noise. This amplification is the reason 92% of incidents can be closed by automation and AI, leaving human analysts free to hunt for sophisticated threats rather than managing alert fatigue.

Can the ACDC integrate with our existing tools and platforms?

Absolutely. ACDC is built to integrate. We connect with your existing SIEM, endpoint protection, cloud security services, identity systems, email platforms and network monitoring. We don’t replace your tools. We bring data together from all of them, add context, remove noise and create unified visibility. Your existing security infrastructure becomes more effective through expert-led analysis and coordinated response across all domains.

Who responds when a threat is detected, and how fast does it happen?

Threats detected by ACDC are immediately investigated by our certified SOC analysts. When a genuine threat is confirmed, containment begins within seconds. We don’t escalate to you and disappear. We work with your team to understand threat scope, execute containment actions, guide remediation and verify effectiveness. This partnership model means rapid response paired with your operational control and strategic oversight. You’re not alone during an incident.

How does ACDC help with compliance and regulatory requirements?

Compliance frameworks like HIPAA, PCI, ISO 27001 and FCA requirements all mandate active security monitoring and documented incident response. ACDC directly addresses these requirements through 24/7 monitoring across your entire environment, formal incident response processes, detailed audit trails and compliance-ready reporting. We generate reports showing active monitoring in operation, threats detected, response actions taken and security controls operating effectively. This documentation helps you meet regulatory expectations while reducing burden on your internal team. Compliance becomes demonstrable, not aspirational.

Do I have to be an MXDR customer to make use of ACD?

No. Active Cyber Defence (ACD) can be delivered as a standalone service to complement your internal security team or alongside existing security services from SCC.

While ACD naturally complements SCC MXDR by extending detection and response into proactive threat disruption and exposure management, it does not depend on a specific security stack. It can integrate with your current tools and security operations to enhance visibility, prioritisation, and defensive actions.

This provides flexibility to adopt ACD independently, or as a strategic layer on top of MXDR to further strengthen your overall security posture.
