Legacy gives you essential protection against everyday risks — things like viruses, malware, and keeping your devices patched. The challenge is that most cyber attacks in 2025 no longer start with an obvious virus.

Hackers now use “living off the land” techniques - they log in rather than break in, using stolen passwords, fake emails, and gaps in cloud settings to tiptoe through a system without triggering basic antivirus tools.

Because of that, the main risks with a Legacy-only setup are:

• Email attacks get through: modern phishing and impersonation aren’t stopped by basic filtering.
• Stolen passwords go unnoticed: attackers use legitimate tools to blend in.
• Slow detection: without 24/7 monitoring, suspicious activity can sit undetected.
• Backups are vulnerable: standard backups can be altered or deleted during an attack.
• Cloud systems are exposed: attackers target Microsoft 365 misconfigurations that Legacy does not cover.
• Limited response: recovery takes longer and may cost more without enhanced protection.

Legacy is a safe starting point, and it protects against the traditional threats everyone expects — but most real-world attacks now bypass those basics. That’s why many SMEs choose Proactive when they want meaningful protection against how attacks actually happen today.
