Like many cybersecurity companies, Securonix has added XDR (eXtended detection and response) to its branding, marketing and outreach to potential MSSP partners.The evidence? Through the end of 2021, Securonix positioned mainly as a "Next-Gen SIEM" (security information and event management) software company. Fast forward to 2022, and every Securonix news announcement now mentions XDR right in the first paragraph.100% SaaS ARR (annual recurring revenue) growth; 240% Year-over-Year new MSSP logo bookings growth; and 100% Year-over-Year employee headcount growth, eclipsing 1,000 employees worldwide, the company said. The growth statistics certainly look impressive -- though actual revenue dollar figures were not disclosed, and we don't know how much revenue that MSSPs influence for Securonix.Meanwhile, M&A activity as well as investor activity across the SIEM, SOAR and XDR markets remains strong. Example deals include:February 2022: Infinite Group Inc. (IGI) acquired Pratum; January 2022: Google Chronicle acquired Siemplify; and November 2021: Angel investors are backing BitLyft. We'll be watching to see if or how the SIEM, SOAR and XDR markets further converge.
