The tool-sprawl problem in MSP security stacks

Here is a question I ask MSP owners fairly often: how many security tools are running across your client environments right now? Not how many you intended to buy. How many are actually deployed, licensed and generating alerts.

The answer is almost always somewhere between 6 and 10. Sometimes more. SentinelOne or CrowdStrike on the endpoint. Fortinet or another firewall vendor on the network perimeter. Microsoft 365 with Defender generating its own alert stream. A SIEM somewhere, maybe LogRhythm or Microsoft Sentinel. Possibly a vulnerability scanner. A separate email security gateway. ConnectWise or another PSA ingesting tickets from all of them.

Each of those tools was bought for a reason. Each of them works, in isolation. The problem is that none of them talk to each other in any meaningful way. An alert fires in Defender. Another fires in SentinelOne. A third fires in the firewall logs. All three relate to the same attacker moving through the same client environment. But without correlation across those three surfaces, your engineers see 3 separate tickets, not 1 incident. And the attacker has already moved.

That is what tool sprawl actually costs. Not the license fees, though those are real. The cost is in the detection gap that exists between your tools, which is exactly where modern attacks are designed to operate.

What Open XDR actually does (in plain English)

Open XDR is an architecture, not a product. The core idea is a telemetry layer that sits above your existing tools and ingests signals from all of them, regardless of vendor. Endpoint data from SentinelOne. Network data from your Fortinet firewall. Identity signals from Entra ID. Email signals from Microsoft 365. Cloud activity from Azure or AWS. All of it feeding into a single detection engine that can correlate across surfaces.

The "open" part matters. A closed XDR platform, like the one CrowdStrike sells, works beautifully if every tool in your stack is from CrowdStrike. The moment you have a Fortinet firewall or a non-CrowdStrike EDR, you are outside the correlation model. Open XDR is vendor-agnostic by design. It connects to 400+ tools and ingests data regardless of who made the sensor.

What this means in practice is that a credential stuffing attack that compromises a Microsoft 365 account, moves laterally using an application on the endpoint and exfiltrates data through a misconfigured cloud storage bucket shows up as one correlated incident, not three unrelated alerts. The detection quality is fundamentally different when you have cross-surface visibility rather than per-tool visibility.

For MSPs, this architecture is particularly relevant because your clients run heterogeneous stacks. They didn't buy everything from one vendor, and they're not going to. The only realistic path to unified visibility is a layer that sits above the stack and connects what's already there

How enhanced.io sits above your existing stack

enhanced.io is Open XDR delivered as a managed service for MSPs. Our Open XDR platform is vendor-agnostic and connects to the tools MSPs already run. On top of that platform, we run a 24/7 human-led SOC that reviews, validates and escalates what the platform surfaces.

The integration model is additive. If a client is running SentinelOne, we connect to SentinelOne. If they're on Fortinet, we connect to Fortinet. If they're on Microsoft 365 Business Premium, we pull in identity signals, email signals and cloud activity. Nothing gets replaced. The existing tools stay in place. We add the correlation layer and the analyst coverage they were missing.

For MSPs managing multiple clients, this matters because every client's stack is slightly different. One runs CrowdStrike. Another runs SentinelOne. A third has a Barracuda email gateway. enhanced.io handles that heterogeneity across your entire client base from a single multi-tenant console. You get unified visibility into all of them without having to standardize every client on the same toolset.

The platform also feeds directly into the full-spectrum security coverage model we've built for MSPs. Endpoint, network, identity, email, cloud and application visibility, correlated and monitored by analysts who understand the MSP operating model.

Keep your tools, get MDR outcomes

The conversation MSPs need to have with clients is not about replacing tools. It is about the gap between tools, which is where incidents actually start. 

A client who runs SentinelOne and Fortinet and Microsoft 365 has spent real money on security. They're paying for endpoint protection, network perimeter defense and email security. What they don't have is anyone watching for an attacker who moves through all three. That is the MDR conversation, and it's a much easier sell than asking them to change what's already in place.

enhanced.io's model is built specifically for that conversation. Keep SentinelOne. Keep Fortinet. Keep Microsoft 365. Add the Open XDR layer that connects them and the 24/7 SOC that watches what the platform surfaces. The result is detection and response capability that no single tool in the stack provides on its own.

For MSPs looking to add a managed security practice without a rip-and-replace conversation, this is the architecture that makes it possible. The tools are already there. The gap is the layer that connects them. That is what we provide.

About enhanced.io

enhanced.io is a channel-only Open XDR SOCaaS built exclusively for MSPs, with 400+ integrations across endpoint, network, cloud, identity and IoT/OT. enhanced.io does not sell directly to end clients. The platform connects to the security tools MSPs already run, including SentinelOne, Fortinet, Microsoft 365, ConnectWise and N-able, and adds a vendor-agnostic Open XDR correlation layer above them. A human-led 24/7 SOC monitors, triages and escalates threats across all integrated surfaces. The delivery model is channel-only and white-label: MSP partners deliver enhanced.io’s capabilities under their own brand.

enhanced.io also provides Fractional Security Director services that help MSPs translate security operations into client-facing business narratives, compliance evidence and QBR content. enhanced.io serves MSPs and MSSPs working with organizations in the 10 to 1,000 employee range. The business was built channel-only from day one and has no direct sales motion to end clients.
