Content Disarm & Reconstruction (CDR): 8 Best Vendors in 2026

CDR is a proactive file sanitization technology that neutralizes potential threats by removing malicious artifacts from files. Instead of trying to identify malware, CDR disassembles a file, strips out unsafe elements like macros or embedded code, and rebuilds a safe, usable version for end users.

גישה זו מבטיחה שקבצים הנכנסים לארגון באמצעות דואר אלקטרוני, הורדות, העברות קבצים או כלי שיתוף פעולה, יהיו נקיים ממטענים זדוניים נסתרים, ומגנים על הארגון מבלי לשבש את הפרודוקטיביות.

CDR breaks a file into components, validates the structure, removes active or non-compliant elements like macros, scripts, exploits prone objects, malformed markup, and suspicious links, then reconstructs a safe file that preserves content and usability. Originals can be quarantined or sent to a sandbox for forensic analysis, depending on policy.

• Prevents known and unknown threats, including zero day and evasion techniques
• Delivers clean files in seconds, with minimal user friction
• Reduces reliance on signatures, detonation, and human judgment
• Improves compliance with secure file handling and data protection
• Creates consistent policy enforcement across email, web, SaaS, and OT paths

CDR does not replace antivirus, sandbox, EDR, or SEG. It complements them. Detection tools still provide insight, correlation, and response, while CDR reduces risk at the point of file ingress by rebuilding safe files first.

Choosing the right CDR vendor is critical for protecting your organization from file-based threats, zero-day vulnerabilities, and advanced persistent threats. Below is a curated list of the top 10 enterprise-grade CDR vendors in 2025. Each vendor is evaluated for its core capabilities, deployment flexibility, integration support, and real-world use cases.

OPSWAT Deep CDR™ Technology is the company’s prevention‑first file sanitization engine within the MetaDefender® platform, purpose‑built for critical infrastructure and trusted file workflows. In independent evaluations, Deep CDR™ Technology became the first CDR solution to achieve 100% Protection and 100% Legitimate Accuracy in SE Labs testing.

Deep CDR™ Technology verifies true file type and structure, creates a safe “placeholder,” disarms risky objects including macros, scripts, malformed structures, then regenerates a clean file with fully usable. Deep CDR™ Technology also augments with OPSWAT’s Metascan™ Multiscanning, Proactive DLP™, and Adaptive Sandbox technologies to enable multi-layered file security.

• Zero‑day neutralization without signatures or heuristics; protection against obfuscation and steganography tactics.
• Proven efficacy: 100% in SE Labs CDR test; additional third‑party validation by SecureIQLab.
• Flexible deployments across email, web, uploads, downloads, portable media, ICAP/API connectors, and gateways.

• Evaluate and verify true type/consistency, prevent masquerading
• Create and hold a safe placeholder
• Disarm and rebuild approved elements; regenerate structures
• Deliver clean, functional files with audit details

ReSec focuses on Zero‑Trust gateway protection with its ReSecure platform, combining intelligent file‑type verification, multi‑engine detection, and real‑time CDR to eliminate both known and unknown file‑borne threats while preserving usability.

ReSec CDR identifies true file types including embedded/archived content and then rebuilds fully functional replicas for unknown‑threat prevention. Originals are quarantined outside the organization for forensics.

• Quarantine‑by‑design of source files outside the network
• Scalable, low‑latency architecture suited to high‑volume gateways
• Channel coverage: email, web, removable media, file servers, and API flows

• Quarantine originals externally
• Identify true file type
• Reconstruct clean replicas and deliver to destination

In February 2025, Menlo Security acquired Votiro, bringing Votiro’s advanced CDR and data security (DDR) into Menlo’s secure enterprise browser and workspace security portfolio that unites file safety across browser, email, collaboration tools, and API flows.

Votiro’s positive‑selection CDR rebuilds files by allowing only known‑good elements, ensuring safe documents across ingress/egress channels; integrated within Menlo, it complements Zero Trust Access.

• Seamless workspace security: file flows protected across browser, email, SaaS, and collaboration apps
• Enterprise scale with transparent user experience (no workflow disruption)

• Intercept file movement (browser/email/API/collab)
• Deconstruct & positively select safe components; rebuild clean file
• Deliver safe, native‑format files to users and apps

Sasa’s GateScanner protects “every channel” (email, web downloads, secure MFT, removable media, ICAP/API) with CDR, originally designed for high‑threat, critical networks and widely adopted across government and ICS/OT.

GateScanner deeply deconstructs files (including archives), strips active/risky content, and reconstructs policy‑compliant versions. It also offers cross‑domain transfer with GateScanner Injector (optical data diode) to move sanitized data across segregated networks.

• Inline email security (SEG or SMTP relay), browser download sanitization, removable‑media kiosks, and secure MFT
• Active‑active scale and policy granularity; supports hundreds of file types
• Microsoft ecosystem integrations (e.g., AppSource listing)

• Disarm & reconstruct to eliminate zero‑day/polymorphic threats.
• Deliver sanitized content across chosen channel (email/web/MFT/USB)

Glasswall delivers zero‑trust file protection through its CDR Platform (Halo), widely used by defense, intelligence, and highly regulated sectors; recent integrations (e.g., with ReversingLabs) add threat intelligence context to CDR operations.

Glasswall validates files against the manufacturer’s known‑good specification, repairs deviations, removes risky elements per policy (e.g., macros, links), and rebuilds clean files that are aligned with NSA ISG guidance for inspection/sanitization.

• Kubernetes‑based scalability, REST/ICAP endpoints, and desktop/clean-room UX
• Defense‑grade deployments and technical documentation for policy mapping

• Inspect: break down and validate file structure.
• Rebuild: correct/repair invalid structures.
• Clean: remove high‑risk components by policy.
• Deliver: semantic checks and output of clean file at speed.

Everfox (the rebrand of Forcepoint’s federal unit) incorporates the Deep Secure CDR heritage acquired by Forcepoint in 2021. Everfox promotes Zero Trust CDR (a.k.a. Threat Removal) across cross‑domain and threat‑protection portfolios, also pairing with hardsec RBI in new cloud services.

Everfox CDR extracts valid business information, verifies structure, and builds a brand‑new file to carry the information onward to prevent even unknown malware and exploits from surviving the transformation.

• Pixel‑perfect, fully revisable output; deterministic prevention
• Cross‑domain pedigree and high‑assurance deployments for government/critical missions

• Extract business data from the original file
• Verify the extracted information is well‑formed
• Rebuild a new file per specification, discard or store original
• Deliver the safe, editable result

Check Point’s Threat Extraction (TE) is a CDR capability spanning Quantum network gateways and Harmony endpoint/email, operating alongside Threat Emulation sandboxing and powered by ThreatCloud AI intelligence.

Threat Extraction preemptively removes active content (macros, embedded objects, scripts, links), optionally converts to PDF, and delivers clean files in seconds, while the original can be released post‑sandbox verdict when allowed.

• Strip exploitable components on ingress
• Reconstruct a safe version (often near‑instant)
• Optionally release the original after sandbox approval (policy‑based)
