Won Global Infosec Award for Protective DNS
We're proud to have won an award from Cyber Defense Magazine for our Protective DNS solution.
Series A Extension
We raised another $15 million in Series A Extension from Insight Partners to continue our mission of making the internet safer and workplaces more secure.
We acquired Guardian
We acquired Guardian, a privacy-protecting firewall for iOS and Android. The "smart firewall" blocks apps from sharing users' personal information with third parties.
Our Series A
We raised $33.5 million from Insight Partners and Arthur Ventures. We were one of the biggest cybersecurity Series A's in 2021–we were tied for third with four other companies.
Massive growth
Despite a worldwide pandemic, we grew our team, added new functionality to our product, and added more customers than we ever had at that point.
Team triples in size
We were still small compared to where we are now. By this point, we were big enough to really put some muscle behind expanding our features—Roaming Clients in particular.
Webshrinker is acquired
Webshrinker is what powers DNSFilter's threat efficacy. This was a momentous occasion for us, and we were able to expand our product offering.
Our first investor
This was just the beginning of external buy-in in DNSFilter.
Our first customer
It was a big milestone for us as we were able to prove that we had a solution that was necessary—and works.
DNSFilter is founded
There were just three of us when we started out. Today we're over 140.
