The cryptocurrency market is in a meltdown. Bitcoin prices are down nearly 60% from their December highs, and major banks are cutting off credit card access to crypto exchanges—no surprise in the wake of a mania that saw everyone and their dog sharing hot crypto tips.

Meanwhile, the cyber-security industry is experiencing its own bubble bursting, albeit in much less dramatic fashion. As Reuters reported last month, investors are at last acknowledging the obvious: There are too many VC-bloated start-ups chasing too few clients, while unicorns are morphing into zombies struggling to find an IPO or other exit.

This situation may explain a recent flurry of press releases from cyber firms like Tenable, Cylance and Duo. The releases tout revenue growth and appear intended to assure anyone who will listen that “hey, we’re surviving the cyber shake-out just fine thank you very much.”

It’s hard to say for now which firms will be left standing at the end of 2018 but, for now, it’s clear the peak of the cyber-boom, when VCs would shower money on any company with blinky lights, is over. The investor uncertainty, though, is just one part of the cyber story. There’s also the more important question of whether all these companies have helped harden the country against hacking, and the answer appears to be yes.

Based on recent conversations with ordinary executives, I’ve found cyber-literary has shot up. While hackers are still getting through (they always will), managers and general counsels are finally attuned to the threat and doing something about it.

This change is also trickling down to more humble enterprises. I met a company this week called CyberSight, which offers free and low-cost ransomware protection to the likes of small businesses and county governments, and many of them are actually implementing it. This is a welcome change from a year ago when too many companies blew off cyber defense as an exotic affair they didn’t need.

So let’s celebrate cyber victories where we can find them. Finally, returning to crypto, don’t forget it’s tax time—if you bought or sold, here’s a plain English Q&A to get you through. Have a great weekend.
