I've heard from my IT team that our new security system uses machine learning techniques to block all VPNs. Is that actually true, or could it just be a scare tactic to keep us from using VPNs?

Yeah, it's definitely possible for firewalls to identify VPN traffic. They might not see what’s inside the data, but they can recognize patterns that indicate VPN use. It's not just about the AI buzzwords; the technology is getting better at this.
Most companies use TLS interception, so any attempts to hide traffic will stand out. If a bunch of data is constantly flowing to one IP, they can usually guess it's a VPN. It's not that hard these days!
It's especially easy to spot VPN traffic if the DNS requests aren't encrypted. No fancy technology needed—just some basic monitoring and a bit of common sense!
That's interesting! I had no idea it could be that straightforward.
Absolutely, many systems have had the ability to detect VPN traffic for a while. As firewalls evolve, they're getting smarter at blocking anything they can’t decrypt.
Exactly! It’s really about how data gets handled at the firewall level.
Thanks for clarifying that! So they can tell just by the traffic patterns?
