Breach ready: understanding your attack surface

The cyber threat landscape has never been more complex. Attackers are constantly scanning for weak points, exploiting overlooked assets, and targeting both technology and people. For organisations, being breach ready is no longer about reacting when an incident occurs. It’s about proactively understanding, monitoring, and managing the attack surface so that risks can be reduced before they are exploited.

Integrity360 helps businesses across industries take this proactive stance, combining consultancy, managed services, and advanced detection and response capabilities. In this blog, we’ll explore what the attack surface is, why it matters, and how Integrity360 services can help organisations strengthen their resilience.

What is an attack surface?

An attack surface is the sum of all the entry points that an adversary could exploit to access your systems or data. Years ago, this might have meant a handful of servers and endpoints inside a corporate network. Today, attack surfaces have expanded far beyond the data centre.

• Digital assets: Websites, APIs, cloud platforms, and SaaS applications.
• Devices: Endpoints, mobile devices, IoT, and operational technology systems.
• People: Employees, contractors, and partners susceptible to phishing or insider risks.
• Third parties: Vendors and service providers integrated into your environment.

The challenge is that the attack surface is constantly evolving. Without visibility, organisations risk leaving blind spots that adversaries will quickly exploit.

Why being breach ready matters

No organisation can be completely immune to cyber attacks, but preparations can make all the difference between a contained incident and a full-scale breach. When businesses lack a clear picture of their attack surface, several risks arise:

• Shadow IT and forgotten assets can create unseen exposures.
• Cloud and remote working expand access points that are often misconfigured.
• Regulatory compliance under GDPR, NIS2, and DORA requires proof of strong controls.
• Financial and reputational costs of breaches continue to rise each year.

Being breach ready means knowing your exposures, reducing them, and having the right people, processes, and technologies in place to respond effectively.

Gaining visibility with integrity360

Visibility is the foundation of breach readiness. Integrity360 provides several services designed to map and monitor your attack surface:

• Cyber Risk & Assurance (CRA) assessments deliver consultancy-led insight into risks across IT, OT, cloud, and third parties.
• Managed Asset Security ensures continuous discovery, classification, and monitoring of digital assets, reducing blind spots.
• Continuous Threat Exposure Management (CTEM) as a Service provides an ongoing cycle of identifying, prioritising, and remediating exposures, focusing on the risks most relevant to your business.

With these services, organisations gain a clear and up-to-date view of their digital footprint, making it far harder for attackers to exploit overlooked assets.

Validating and reducing exposures

Once the attack surface is visible, the next step is reducing exposures and validating defences. Integrity360 offers a broad portfolio of proactive testing and protection services:

• Penetration Testing and IoT/OT testing uncover weaknesses before adversaries do.
• Red Teaming simulates real-world adversary behaviour to assess resilience under pressure.
• Breach & Attack Simulation provides continuous validation that security controls are performing effectively.
• Identity & Access Management services help enforce least privilege and multi-factor authentication, addressing one of the most common attack vectors.
• Cloud Security services mitigate misconfigurations and secure modern architectures.

These measures ensure your defences are layered, adaptive, and resilient.

Preparing for the inevitable

Even with strong controls, no organisation is immune. That’s why breach readiness also means planning for response and recovery. Integrity360 provides:

• Managed Detection & Response (MDR) for 24/7 monitoring and containment of threats.
• Incident Response (IR) services that deliver expert-led investigation, remediation, and recovery, alongside readiness assessments and playbook development.
• Darktrace Security Operations Centre (dSOC) for AI-driven detection across email, cloud, endpoint, and network environments.
• Business Continuity and Incident Response Planning to develop and rehearse cyber crisis strategies through exercises and simulations.

In addition, Threat Intelligence services provide tailored insights into the tactics of threat actors targeting your sector, enabling a proactive rather than reactive defence.

Being breach ready begins with understanding your attack surface. In a digital landscape where assets, users, and suppliers are in constant flux, static defences are no longer enough. Organisations need continuous visibility, proactive validation, and robust incident response strategies.

Integrity360 supports clients through every stage of this journey — from attack surface discovery and risk assessment to testing, managed detection, and incident response. With this breadth of expertise, businesses can significantly reduce their risk and ensure they are prepared to withstand and recover from cyber attacks.

Breaches may be inevitable, but with the right preparation and the right partner, their impact doesn’t have to be. Integrity360 makes sure your organisation is not only secure but truly breach ready.
