THE PROBLEM

Microsoft Gave You the Tools. It Didn’t Give You
Unified Security.

Microsoft E3/E5 is the most common enterprise security consolidation play – Defender, Sentinel, Entra, and more under one license. But consolidating vendors isn’t the same as unifying security.

split 1

Microsoft tools don't fully talk to each other – let alone the rest of your stack

Defender, Sentinel, and Entra each see their slice of the environment. Without a unifying layer, your team is still jumping between consoles and manually stitching findings together.

Non-Microsoft gaps stay invisible

Your environment isn't 100% Microsoft. Cloud workloads, SaaS apps, third-party identity tools, and CI/CD pipelines create exposure chains that Microsoft tools simply don't see – and attackers know it.

E5 is expensive. Most organizations underutilize it.

E5 licenses come packed with capabilities that never get fully deployed or integrated. Without a layer that activates and connects those capabilities, you're paying for potential, not protection.

Selecting and deploying security tools in a siloed way that does not share context and alerts is no longer sufficient.

Activate Remediation Through Tools You Already Own

Mesh orchestrates systematic attack path elimination using your existing Microsoft and non-Microsoft investments – prioritized by real business risk.
THE OUTCOMES

Make Your Microsoft Consolidation Bet Pay Off.

See and eliminate complete post-phishing attack paths before attackers find them

One view across Defender, Sentinel, Entra, and beyond

Stop bouncing between Microsoft consoles. Mesh unifies signals across your entire stack into a single continuously updated attack path graph – Microsoft and everything else.
One view across Defender

See the gaps Microsoft can't

Mesh reveals how non-Microsoft exposures – cloud misconfigurations, SaaS blind spots, third-party identity gaps – chain with Microsoft findings to create attack paths your E5 investment never surfaces alone.

Activate the E5 capabilities you're already paying for

Mesh maps your current Microsoft deployment against your actual attack surface – identifying underutilized E5 capabilities and showing exactly where activating them would break real attack paths.

What is Automated Security Control Assessment (ASCA)?

What is Automated Security Control Assessment? Automated Security Control Assessment (ASCA) is the continuous, machine-driven process of testing, validating, and verifying that an organization’s security controls are configured correctly, operating as intended, and actually capable of stopping the threats they were designed to prevent. Rather than relying on periodic manual audits or point-in-time pen tests, […]

Security Analytics and Intelligence Layer (SAIL): SAIL’s Role in CSMA

Security teams today aren’t short on data. They’re drowning in it. The average enterprise operates 83 security tools across 29 vendors. Each one generates alerts, scores, and findings – a flood of signals that no team can meaningfully process. And yet, despite all of this instrumentation, 67% of breaches are still missed by internal teams.  […]

The Five Layers of CSMA (Cybersecurity Mesh Architecture)

The Five Layers of CSMA: A Guide for Enterprise Security Teams The average enterprise today deploys 83 security tools across 29 vendors. And yet, less than half of breaches are detected by internal teams.  More tools haven’t translated to better security – they’ve produced more dashboards, more alerts, and more noise, without answering the question […]
