Document security with traditional antivirus vs CDR technology

Antivirus alone is not enough for your business: let's talk document security

22nd May 2025 Kat Korson

Most businesses still open and share files much as they have for years, but the threats hiding inside those files have become far more sophisticated. Hackers are using everyday documents like PDFs, Word files, and spreadsheets to deliver ransomware or steal sensitive information as soon as someone opens the files.

The problem is, traditional antivirus software often isn't enough to catch these threats. It relies on recognising known patterns, which means anything new or cleverly disguised can easily slip through.

At Red Eagle Tech, we take a smarter approach to file protection. It's called Content Disarm and Reconstruction (CDR). Instead of trying to guess which files are dangerous, CDR assumes every file could be risky. It strips out potentially harmful content and rebuilds a clean version that's safe to use. So let's talk honestly about document security and why relying on antivirus alone might be leaving your business exposed.

Antivirus software actually doesn't catch everything

Traditional antivirus tools rely on something called 'signature-based detection', meaning they only look for known threats. But attackers are constantly changing their methods.

If a threat hasn't been seen before or is cleverly hidden, your antivirus might not pick it up.

CDR works differently. It doesn't try to identify the bad stuff. It just removes anything that might be unsafe, like embedded code or macros. Then it rebuilds the file so it's clean and safe. That means it can stop both familiar threats and new, unknown ones.

Good security doesn't have to be inconvenient

People often worry that stronger protection will make files harder to open or use. That may have been true in the past, but not anymore. Today's CDR tools keep your files looking and working like they always have.

Our API works quietly in the background, scanning and cleaning each document before it reaches your systems. To your team, it's business as usual, just with added peace of mind.

Small and medium businesses are often targeted

There's a myth that hackers only go after big companies. In reality, smaller businesses are often an easier target. In fact, 59% of medium-sized UK firms reported a cyberattack last year. Recovering from a document-based breach costs, on average, £5,000, not to mention the downtime and lost trust.

We believe document security should be affordable. That's why we offer CDR protection starting from just £50 a month.

It's easier to add than you might think

Security upgrades often sound like a big project. But our CDR API can be integrated with just a few lines of code. There's no new infrastructure to set up, and no servers to maintain. It's a fully managed cloud service, designed to fit right into your existing systems. You don't need to be a large company or have a full-time IT team to benefit.

This isn't just for regulated industries

Yes, sectors like finance and healthcare have strict compliance rules. But document-based threats don't care what industry you're in. If you receive files from customers, partners or applicants, you're at risk. We've seen our CDR solution used across a wide range of businesses. Some common examples include:

  • File upload forms and portals
  • Scanning email attachments before they reach inboxes
  • Shared drives and cloud storage
  • Exchanging documents with suppliers or contractors

Why antivirus isn't enough

Antivirus software tries to block known threats. CDR takes a different path. It removes any risky content before the file ever touches your network.

With Red Eagle Tech's CDR API, you'll get:

  • Seamless integration with your current setup
  • Fast file cleaning (usually under a minute)
  • Support for all major document formats
  • Cloud-based protection that's always up to date
  • UK-based processing to support regulatory compliance
