August 10: DNSFilter has acquired Guardian and its firewall plus VPN platform. Combined with DNSFilter's Domain Name Service layer security, this platform will allow the firm to offer a secure web gateway (SWG). “Secure web gateway plays a critical role in modern security strategies, enabling organizations to better secure access to the service edge,” said Ken Carnesi, CEO and co-founder, DNSFilter, in a press release. “But the technology is tired – incumbents have not kept pace with the evolving threat landscape or customer needs around service and support. Combining best-in-class Domain Name System (DNS) layer security with firewall + VPN presents a massive business opportunity and alleviates the pain points customers face with legacy SWG technology.” Terms of the deal were not disclosed.
