Antivirus software is still widely used, but it’s no longer enough to keep businesses secure.
Modern threats are faster, smarter, and more evasive than ever. From ransomware to credential theft, cybercriminals are using tactics that slip past traditional tools.
That’s why more SMEs are now turning to Endpoint Detection and Response (EDR) a smarter, more proactive way to detect and stop threats in real time.
This blog post explains what EDR is, how it differs from antivirus, and why it’s fast becoming essential for modern IT security.
What Is Endpoint Detection and Response?
EDR is an advanced form of endpoint security designed to detect, investigate, and respond to threats in real time. It monitors activity across all endpoint devices – your desktops, laptops, servers, and mobile devices – and flags suspicious behaviour as it happens.
Unlike traditional antivirus, which focuses on known malware signatures, EDR tools use behavioural analysis and machine learning to identify emerging or previously unseen threats. When an incident occurs, EDR can contain the threat automatically and provide forensic-level detail to support remediation.
In short: EDR doesn’t just stop threats. It tells you what happened, how it happened, and what needs to be done next.
Why Antivirus Alone Isn’t Enough
Antivirus tools are reactive. They can be effective against known viruses, but they struggle with today’s more sophisticated attacks, especially those that don’t rely on malicious files.
Common tactics that bypass antivirus include:
- Fileless attacks that run directly in memory.
- Zero-day vulnerabilities exploited before patches are available.
- Credential theft and lateral movement within networks.
- Ransomware that stays undetected until it’s too late.
For SMEs using cloud platforms, these risks are especially relevant. Without advanced endpoint protection, many of these threats will go unnoticed, until they cause real damage.
Why EDR Matters for Irish Businesses
Increased cloud adoption, hybrid working, and growing compliance demands mean that even smaller businesses need greater visibility and control over their IT environment.
EDR is particularly relevant for:
- SMEs that handle sensitive client data.
- Professional services firms with remote or mobile staff.
- Regulated industries preparing for NIS2 or similar frameworks.
- Businesses seeking or renewing cyber insurance.
- Any organisation aiming to reduce downtime and strengthen resilience.
The misconception that EDR is “just for large enterprises” is quickly becoming outdated. Today, cost-effective, fully managed EDR solutions are accessible to all sizes of business, and in many cases, essential.
Key Capabilities of EDR
EDR platforms typically offer:
- Real-time detection of malicious behaviour.
- Automated threat response, such as isolating infected endpoints.
- Incident analysis with timelines and root cause data.
- Centralised visibility across all endpoints in your environment.
- Integration with other security tools, such as firewalls and SIEMs.
At Infinite Technology, we provide Bitdefender EDR as part of our managed cybersecurity offering, giving our clients enterprise-grade protection backed by hands-on support and proactive monitoring.
EDR vs. MDR: Understanding the Difference
While EDR is the software platform, Managed Detection and Response (MDR) adds the human layer. MDR services combine EDR with 24/7 security monitoring, expert analysis, and escalation. Which is ideal for businesses that need coverage outside working hours or lack an in-house security team.
We offer both. For many of our clients, a managed EDR and MDR package ensures incidents are not only detected, but also investigated and resolved. All without added burden on internal teams.
Is EDR Right for Your Business?
If your business is still relying solely on antivirus, or if you’re unsure how well your current defences would hold up against a modern threat? Well then, EDR is worth serious consideration.
It’s particularly well suited to businesses that:
- Use cloud platforms.
- Operate in professional, legal, finance, or technical services.
- Have remote or hybrid teams.
- Require greater visibility across devices.
- Are preparing for compliance or insurance-related IT reviews.
