Breaking Down Fidelis XDR: What Every Enterprise Should Know

Enterprise security teams are drowning in complexity. Multiple tools cover different layer endpoint, network, cloud, and email—but none of them see the full picture. Attackers take advantage of this fragmented visibility, moving laterally, hiding in encrypted traffic, exploiting Active Directory (AD), and slipping through gaps in traditional monitoring.

The result?

• Security teams juggle siloed alerts with no context.
• Encrypted traffic blinds conventional inspection tools.
• AD vulnerabilities remain open doors.
• Retrospective investigations are incomplete or too late.

This is the reality: blind spots create opportunities for attackers.

You need full visibility across endpoints, network, cloud, email, and Active Directory. But modern environments span remote users, cloud workloads, encrypted traffic, and growing attack surfaces. Without clear visibility, you stay reactive.

Why Traditional Tools Leave You at Risk

• Isolated insights: Each tool shows only its own layer. An attacker moving from email to endpoint to cloud? You might never see the path.
• Alert noise: You sift through dozens or hundreds of alerts. Then you miss real threats.
• Encrypted blind spots: Most enterprise traffic is encrypted. If tools don’t inspect full sessions, you miss hidden threats and malware.
• AD risks ignored: Active Directory often holds credentials to everything. Misconfigurations and privilege misuse go unnoticed.
• No history for hunting: After a breach, you may lack session logs and forensic data to trace it.

What You Should Expect from Enterprise-Grade XDR

1. Unified visibility across all layers—endpoint, network, cloud, identity.
2. High-confidence alerts—noise reduction with context.
3. Automated containment—speed matters.
4. Historical forensics—search past sessions and events.
5. Built-in deception—see attacker behavior rather than filter it out.

How Fidelis Elevate® Delivers on That Promise

Fidelis Elevate® XDR stands out by delivering visibility and defense that go beyond surface-level integration. It brings together patented inspection, AD defense, deception technology, and automated response into one unified platform.

Here’s what sets it apart:

1. Deep Session Inspection®

Fidelis uses patented Deep Session Inspection® (DSI) to analyze entire communication sessions, not just packets. This enables real-time detection of hidden threats in network, email, and web traffic. With DSI, enterprises can:

• Inspect encrypted traffic inline without breaking connections.
• Extract and analyze files crossing the network in real time.
• Retain full session context for accurate detection and forensics.

2. Active Directory Defense

With Fidelis AD Intercept™, enterprises gain active defense against AD attacks. The platform detects privilege escalation, lateral movement, Kerberoasting, and misconfigurations, giving teams visibility into one of the most targeted parts of the enterprise environment.

3. Built-In Deception Technology

Unlike static honeypots, Fidelis integrates deception directly into its platform. It creates dynamic decoys, breadcrumbs, and false credentials that lure attackers into traps. Any interaction with these deception elements generates high-fidelity alerts with near-zero false positives.

4. Unified Platform Coverage

Fidelis Elevate unifies network, endpoint, cloud, and AD visibility into one console. With correlated intelligence and automated response, enterprises can:

• Quarantine compromised endpoints.
• Block malicious network connections.
• Disable AD accounts under attack.
• Conduct historical forensics to trace attacker behavior.

Forensic Search & Terrain Mapping

You keep the full session history. You can search back through past activity. You can visualize your network terrain and attacker paths at any moment.

What This Means for Your Enterprise

• Faster detection of threats across multiple layers.
• Clearer alerts, so your team focuses on real risk.
• Quick containment, reducing dwell time.
• Streamlined operations, fewer tools to manage.
• Proactive readiness, based on historical insights and deception.

Practical Steps to Take Now

1. Evaluate if your current tools see full sessions and return history.
2. Test deception is automatic and adaptive.
3. Check if your XDR includes AD monitoring, not just log coverage.
4. See if the platform lets you automate containment (isolate the host, suspend the account).
5. Ask for a live walkthrough—see realistic alert flow, forensic search, and response in action.

Final Word

Enterprises don’t fail because of a lack of data—they fail because of fragmented visibility. Attackers know where the blind spots are, and they exploit them.

You can’t ignore visibility gaps and slow detection any longer. Enterprises need XDR that connects the dots, not just tools that point at separate layers.

Fidelis Elevate® bridges that gap with full session visibility, deception, AD defense, and unified response. In cybersecurity, what you can’t see will hurt you. With Fidelis, you finally see it all.
