The traditional idea of a secure network perimeter is obsolete. Today, the biggest threats come from unsecured, unexpected points – your sprawling attack surface. This includes everything from a misconfigured cloud storage bucket to an unpatched laptop used remotely.
This article defines Attack Surface Management (ASM) and explains why continuous, proactive monitoring is now vital for protecting complex, hybrid businesses against modern, persistent cyber threats.
What is Your Digital Footprint Hiding?
Every new device, cloud service, or remote employee expands your attack surface. For growing businesses, this surface is dynamic and often invisible to traditional security tools.
Why Traditional Firewalls Offer Limited Visibility
If you can’t see an asset, you can’t secure it. The true digital footprint goes beyond your physical office network:
- Cloud Misconfigurations: Incorrectly set permissions on SaaS platforms or cloud storage are common, easy-to-exploit vulnerabilities.
- Shadow IT and Unmanaged Assets: Employees using unapproved apps or personal devices (hybrid environment issues) create security gaps that often go unmonitored.
- External Exposure: Unused domains, lapsed security certificates, or exposed administrative ports all provide low-effort entry points for hackers.
ASM is about gaining complete, continuous visibility into these potential weaknesses, shifting security from a fixed fence to an adaptive shield.
The Core Pillars of Attack Surface Management
ASM is a proactive, disciplined process that Dr Logic integrates into its cyber-first mindset.
1. Continuous Discovery
You must map every single internal and external asset. This is not a one-time audit; it’s continuous.
- Endpoint Inventory: Identifying and monitoring every device used, from the Apple laptops in the design studio to the Windows machines in finance.
- Cloud Mapping: Tracking access points, permissions, and configurations across all cloud services (M365, AWS, etc.).
2. Risk Prioritisation
Once assets are discovered, they must be assessed based on the real threat they pose.
- ASM identifies which vulnerabilities are exploitable and which ones, if breached, would cause the most critical business impact (e.g., data loss, regulatory fine). This allows resources to be focused on high-risk, high-impact exposure, making security practical, not theoretical.
ASM in Practice for Hybrid Environments
For London firms managing a mix of office-based and remote staff using both Apple and Windows, ASM is essential for ensuring security consistency.
Securing the Complex Mix
ASM ensures that security policies and monitoring extend seamlessly across the entire hybrid ecosystem:
- Unified Endpoint Security: Implementing EDR (Endpoint Detection and Response) that reports centrally, regardless of whether the device is macOS or Windows, on-site or remote.
- Proactive Reduction: ASM allows your ITaaS partner to quickly decommission unneeded public-facing services or enforce MFA on remote access points before they are exploited.
By integrating ASM, Dr Logic moves your business from reactive scanning to proactive risk reduction, guaranteeing secure collaboration across your entire digital footprint.
Don’t let invisible vulnerabilities compromise your business.

Actionable Takeaways
- Demand Continuous Inventory: Insist your IT partner maintains a real-time, comprehensive inventory of all your external and internal digital assets.
- Prioritise Exposure, Not Volume: Focus your resources on closing the vulnerabilities that pose the highest, most immediate risk to your compliance and data integrity.
- Integrate Endpoints: Ensure your security solution covers all devices, Apple and Windows, with the same high standard of detection and response.

FAQs
Why is ASM more necessary for hybrid businesses?
Hybrid businesses have a larger, more complex attack surface due to the mix of Apple and Windows devices, numerous cloud services, and remote access points. ASM provides the continous visibility needed to enforce security consistently across this diverse, non-traditional perimeter.
What is the difference between vulnerability scanning and ASM?
Vulnerability scanning is a periodic, scheduled check for known flaws. ASM is continuous and proactive. It constantly maps and discovers all assets (known and unknown) and uses risk scoring to prioritise the most critical, exploitable exposures for immediate closure.
What are common examples of external attack surface vulnerabilities?
Common vulnerabilities include unpatched or misconfigured VPNs, unsecured ports that are open to the internet, lapsed SSL certificates on external websites, and misconfigured permissions on public cloud storage buckets (e.g, S3 or Azure Blob).
