What is Managed Attack Surface Management?
Managed Attack Surface Management, or Managed ASM, is a cyber security service that continuously discovers, profiles, monitors and prioritises the assets and exposures across an organisation’s digital environment.
It helps security teams identify known, unknown and unmanaged assets across IT, OT, IoT, cloud, hybrid and medical device environments. By combining asset intelligence, exposure detection, risk prioritisation and expert remediation support, Managed ASM helps organisations reduce the opportunities attackers have to exploit gaps in their environment.
Integrity360’s Managed ASM service is powered by Armis Centrix Cyber Exposure Management and delivered by experienced cyber security specialists.
Our Managed ASM Solution
Integrity360’s Managed ASM service is underpinned by the Armis Centrix Cyber Exposure Management Platform and delivered by Integrity360’s cyber security experts.
The service provides continuous asset discovery, device profiling, exposure detection, risk prioritisation and remediation support across IT, OT, IoT, cloud, hybrid and medical device environments. It helps organisations build a reliable view of their attack surface, identify unknown or unmanaged assets, understand where cyber risk exists and take prioritised action to reduce exposure.
By combining platform capability with expert oversight, Integrity360 helps security teams move beyond static asset inventories and towards continuous attack surface visibility.
The attack surface visibility challenge
Most organisations now operate across a complex mix of corporate endpoints, cloud workloads, SaaS applications, IoT devices, OT systems, remote users, unmanaged assets and third-party connections. Many of these assets are difficult to track, especially when they sit outside traditional IT inventory tools or are introduced without security team visibility.
That creates a serious exposure problem. Security teams cannot protect what they cannot see. Unknown assets, unmanaged devices, misconfigured systems, vulnerable services and risky behaviours can all create routes for attackers to gain access, move laterally or disrupt operations.
Managed ASM helps solve this challenge by continuously discovering assets, identifying exposures, prioritising remediation and giving security teams a clearer view of the true attack surface.
Defining the Attack Surface
An organisation’s attack surface is the total set of assets that could be exploited by threat actors. These include:
-
IT assets (such as endpoints, servers, and cloud services)
-
OT systems (in critical infrastructure and manufacturing)
-
IoT devices (like smart sensors and industrial IoT)
-
Medical devices (for healthcare organisations)
Every asset type carries unique risks, making it essential to establish continuous visibility and assessment across the entire environment.
The Managed Attack Surface service includes:
-
Continuous asset discovery
Gain real-time visibility of known, unknown, managed and unmanaged assets across IT, OT, IoT, cloud, hybrid and medical device environments.
-
Asset intelligence and profiling
Understand what each asset is, where it sits, how it communicates, what risks it carries and whether it is behaving as expected.
-
Exposure detection and prioritisation
Identify cyber exposures such as vulnerable devices, misconfigurations, insecure services, policy violations and risky behaviours, then prioritise them based on business risk and exploitability.
-
Remediation support
Receive actionable recommendations, ticketing integrations and expert support to help resolver teams reduce high-priority exposures.
-
Advanced threat detection
Detect anomalous behaviour and suspicious asset activity earlier, helping teams respond before incidents escalate.
-
Reporting and continuous improvement
Track exposure trends, remediation progress and attack surface changes over time to support governance, compliance and security improvement.
Service Benefits
-
Discover assets you did not know existed
Build a more complete inventory of assets across IT, OT, IoT, cloud and medical device environments, including unmanaged or previously unknown devices.
-
Reduce exploitable cyber exposure
Identify the exposures attackers are most likely to target and prioritise the actions that will reduce the greatest amount of risk.
-
Improve security across complex environments
Gain visibility across environments that traditional asset management tools often miss, including operational technology, connected devices and specialist systems.
-
Reduce pressure on internal teams
Give internal security and IT teams expert support, prioritised recommendations and clearer remediation workflows.
-
Support compliance and reporting
Use continuous asset visibility, exposure history and remediation tracking to support frameworks such as ISO 27001, NIS2 and DORA. The page already references these frameworks in the FAQ, so this should be brought into the main copy too.
-
Detect risky behaviour earlier
Identify anomalous asset behaviour and suspicious activity before it becomes a wider security incident.
The service is implemented in a continuous and cyclical manner, ensuring constant improvement of security posture and maintenance of that posture in the face of new attack surface exposures

ASM FAQs
What is Managed Attack Surface Management (ASM)?
Managed ASM is a fully managed cybersecurity service that provides continuous visibility, risk prioritisation, and exposure remediation across your organisation’s entire asset landscape—including IT, OT, IoT, cloud, and hybrid environments.
Why is ASM important for cybersecurity?
With the rise of shadow IT, remote work, and IoT devices, organisations face a growing and complex attack surface. ASM helps uncover and manage unknown or vulnerable assets, allowing security teams to prioritise threats and respond before incidents occur.
What does Integrity360’s Managed ASM include?
The service includes continuous asset discovery, exposure intelligence, business-risk prioritisation, remediation orchestration, and validation. It integrates with existing environments and includes optional add-ons such as threat intelligence, remediation resource augmentation, and 24/7 security monitoring.
How does Managed ASM differ from traditional asset management?
Unlike traditional asset inventory tools, Managed ASM continuously identifies exposures and prioritises remediation based on actual risk. It combines AI-driven asset intelligence with expert oversight to proactively reduce cyber threats across the full digital estate.
What is the difference between Managed ASM and Managed ASM+?
Managed ASM covers core visibility and exposure detection. Managed ASM+ adds advanced vulnerability aggregation, deduplication, prioritisation, and complete remediation management—ideal for organisations seeking a more in-depth, hands-off service.
How does ASM support remediation efforts?
Integrity360 works directly with resolver teams to track and manage remediation from start to finish. Optional augmentation provides skilled resources to help tackle backlogs and accelerate the resolution of high-priority exposures.
Can ASM help with compliance and reporting?
Yes. Managed ASM provides continuous documentation of asset status, exposure history, and remediation actions. This visibility supports audit readiness and compliance with frameworks such as ISO 27001, NIS2, and DORA.
What makes Integrity360’s ASM service different?
Integrity360’s service is powered by Armis Centrix and delivered by seasoned experts. It combines deep technical insight, hands-on remediation support, and customisable service tiers, providing a proactive and scalable defence against modern cyber threats.
