EDR vs classic antivirus — the differences

Antivirus today

This section frames the topic "Antivirus today" in the context of EDR vs classic antivirus — the differences. We approach it from the business side — what concrete value or risk it brings to the company.

What you gain

• Significantly reduced risk of ransomware and customer data leaks.
• Compliance with GDPR, NIS2 and cyber insurers' requirements.
• Trust from partners in procurement processes and security audits.

Most common mistakes

• Relying only on antivirus instead of layered protection (EDR + MFA + backup).
• A backup that was never tested — in practice equivalent to no backup at all.
• No anti-phishing training — 90% of incidents start with a click on a link.

What EDR does

Modern IT security works in layers. No single solution protects a company 100% — only a full set of layers (identity, endpoints, network, data, people) provides real effect. In the context of EDR vs classic antivirus — the differences it is worth starting with the basics:

• MFA on all accounts (no exceptions for the board — the most common gap).
• EDR/XDR instead of classic antivirus — it detects behaviour, not just signatures.
• Backups in several locations, including an offline or immutable copy — ransomware cannot encrypt them.
• Patches within 14 days of the vendor's release.
• Anti-phishing training at least quarterly, with simulations.

Vendors

Choosing a tool is usually choosing an ecosystem. Evaluate not only feature-table checkboxes but also the vendor's longevity, the quality of support in Poland, and the cost of integrating with what you already have.

• Ask about the product roadmap and update cadence.
• Check whether support is available in your language and time zone.
• Verify a 3-year TCO (licences + rollout + operations).
• Ask for references from companies of a similar profile and size.

In many cases it is better to pick the second-best tool that you will actually finish rolling out than the best one that stalls in pilot.

Price

A conversation about IT costs starts with a single question: what exactly are we buying?. In practice there are three types of billing: flat fee, hourly, and mixed (base + overage). Each makes sense in a different scenario.

• Flat fee — a predictable cost, best for companies with a stable number of users and systems.
• Hourly — flexible, but hard to budget for a whole year.
• Mixed — the base covers 80% of the work, overage is billed separately; the most common model in SMEs.

What to watch for in a quote

The rate alone is not everything. Check what exactly the price covers, what the hour cap is, how out-of-scope projects are priced and whether travel is billed. The gap between the cheapest and most expensive offer in Poland can be 3–4× — and it usually comes down to what is "in the price" and what is not.
