Antivirus is still doing a job that stopped being the whole job about a decade ago.
In Microsoft's most recent Digital Defense Report, 80% of incidents involved attackers trying to steal data, and more than half of the attacks with a known motive came down to extortion. That's not a virus spreading through your network. That's often a person, logged in with credentials that work, quietly reading through your file shares.
Traditional antivirus is a bouncer with a photo list of known troublemakers. It's good at that. It was never built to notice that your operations manager's account signed in from two states away at 2am and started opening every client folder in order.
That's what managed detection and response adds. The tooling watches behavior instead of just files, and the "managed" part means a human is actually looking at that alert at 2am, because an alert nobody reads is just a log entry.
For a wealth management firm, the real math isn't the ransom. It's the weeks of recovery, the call to every client whose statements sat in that folder, and the cyber renewal that lands right after.
If your current setup is antivirus plus hope, it's worth a real look before your next renewal.
