What Is FDR?

A group of employees working on a computer.

At InQuest®, we’re pioneering cutting-edge tools to define a whole new cybersecurity category: File Detection and Response (FDR). It stands out from conventional solutions like Endpoint Detection and Response (EDR), Network Detection and Response (NDR), and Extended Detection and Response (XDR) by offering an unparalleled ability to address file-borne threats with precision. What does our file-centric approach mean for your security team and organization?

Let’s find out what our FDR is, and who it’s for.

Close the Security Gap

FDR was born from the experiences of SOC analysts and threat hunters entrusted with defending the US Department of Defense against millions of daily emails containing malware, viruses, and phishing schemes from malicious actors attempting to breach the DoD’s systems.

Through that experience, we developed tools to address a critical defense gap that current security technology fails to completely address: files in motion, in use, and at rest.

Files are the root of most user security issues. With this in mind, and with a singular focus on file security, we created FileTAC, our FDR solution to close this critical gap in the security landscape.

Designed for SOC analysts and threat hunters

FileTAC was designed to alleviate the daily challenges faced by SOC analysts and threat hunters. Where other protocols cast their net wide in the hopes of uncovering a threat, we take a different approach.

Four Pillars Of FDR

Deep File Inspection (DFI®) technology

The bedrock of InQuest’s FDR product, FileTAC, is our Deep File Inspection (DFI) technology. DFI goes beyond traditional analysis methods by dynamically dissecting files to reveal hidden layers deep within the content.

Give your threat hunters the upper hand with a comprehensive understanding of malware, exploits, and evolving attack surfaces.

Say goodbye to superficial insights or painfully slow investigations. DFI empowers your team with fast, in-depth analysis.

Let InQuest handle the heavy lifting and give your professionals the actionable intelligence they need to go on the hunt.

FDR Retrohunting icon


With our automated retroactive analysis capabilities, your SOC team can hunt for newly-discovered threats lurking in old files, and root out hidden instances of malware, ransomware, or other security issues.

As new threat intel becomes available, RetroHunt automatically searches for IOCs across files that have already made it onto your system, minimizing threat dwell time.

Uncover historical threats, validate custom detection logic, and monitor for attacks or actors of interest.

Intelligent Orchestration

To streamline detection, response, and remediation, SOCs must find ways to integrate personnel, systems, and tools without drawing team members into mundane, low-value tasks. 

Our Intelligent Orchestration approach involves aggregating, curating, and analyzing terabytes of internal, public, and private threat intelligence data to give your SOC team the pinpoint guidance it needs to enhance SIEMS, enable industry sharing, and strengthen your security posture.

What is FDR IQ Score

IQ Score

Unlike generic file analysis tools, our advanced algorithm combines the expertise of seasoned security analysts, the power of our DFI technology, and multiple security intelligence sources to provide your SOC team with a single score, weighted for both severity and confidence.

Say goodbye to time-wasting score inflation. Our IQ Score technology delivers a discrete, heuristic, and machine learning-driven approach to threat evaluation.

The escalating gradient from 1 to 10 allows your team to use and share a single, precise value for assessment and prioritization.
