As cyber threats become faster, smarter and more multi-dimensional, many MSPs and MSSPs are beginning to realise a harsh truth: endpoint protection alone is no longer enough.

At enhanced.io, we work with service providers across the globe who have traditionally leaned heavily on Endpoint Detection and Response (EDR) to form the backbone of their cybersecurity offering. And while EDR plays a critical role in any layered security strategy, the reality is that endpoint-only tools leave up to 70% of your attack surface completely unmonitored.

Let’s explore why this is such a problem, and what forward-thinking providers are doing about it.

The myth of “enough” protection

Endpoint tools were never designed to do it all. They’re excellent at spotting malware, ransomware and file-based threats on devices, but they simply can’t see into the wider digital ecosystem where modern threats often begin.

Today’s attack surface spans far beyond the endpoint:

• Cloud applications and platforms

• User identities and authentication systems

• Email gateways

• Network infrastructure

• Remote users and unmanaged devices

Relying on EDR to protect these areas is like trying to guard a city using CCTV on only a handful of buildings. You might catch some suspicious activity – but you’ll miss the bigger patterns, the lateral movement and the coordinated attacks.

Why endpoint-only security leaves 70% of your attack surface exposed

We’ve seen it time and time again: MSPs with strong endpoint protection still falling victim to breaches. Why? Because threats often originate or evolve in places endpoints can’t see.

Some examples:

• Credential-based attacks: MFA fatigue, phishing, or stolen passwords often target cloud services like Microsoft 365 – where no endpoint is involved until it’s too late.

• Lateral movement: Once a device is compromised, attackers move silently across your client’s environment via Active Directory or open network ports – unseen by endpoint tools.

• Email compromise: A malicious link gets clicked in a cloud-based inbox, triggering account takeover. EDR won’t detect it because no malware is downloaded to the endpoint.

• Unmanaged or BYOD devices: These may never touch your monitored environment but can still access corporate data or trigger insider threats.

Without visibility across identity, network, email and cloud, most threats are detected far too late – or not at all.

70% of the attack surface? Here’s the math.

According to industry research and internal analysis across our customer base, we estimate that only 30% of threat activity begins and ends on the endpoint. The rest is distributed across:

• Identity and access misuse (22%)

• Cloud service abuse (20%)

• Email-based threats (18%)

• Network-level exploits (10%)

That means endpoint-only solutions leave the vast majority of potential threat vectors outside your line of sight.

What MSPs and MSSPs need instead: Unified, correlated visibility

At enhanced.io, we help providers move from fragmented, reactive security toward proactive, network-wide threat correlation. That means stitching together signals from across endpoints, email, cloud, identity and network into a unified detection and response framework.

This approach is often called Open XDR (Extended Detection and Response) and it’s a game-changer for MSPs who want to:

• Catch threats earlier, before damage spreads

• Reduce false positives and alert fatigue

• Correlate across sources to understand real context

• Deliver higher-margin security services like compliance, vCISO, or co-managed SOC

We call this seeing the full picture – not just the noisy corner that EDR reveals.

Why MSPs are upgrading their security stacks now

The market is changing. Clients are asking tougher questions. Regulators are expecting more. And the cost of breaches is rising, both financially and reputationally.

Providers who continue to rely on endpoint-only tools are putting themselves and their clients at risk. Those who evolve toward unified, correlated threat detection will lead the next generation of cybersecurity services.

At enhanced.io, we’re helping MSPs and MSSPs make that transition – quickly, profitably and with full go-to-market support.
