Tenable Announces Intent to Acquire Alsid
February 2021 by Marc Jacob
Tenable Holdings, Inc. announced that it has entered into a definitive agreement to acquire Alsid SAS (“Alsid”), a leader in Active Directory security. Alsid for Active Directory is a Software as a Service (SaaS) solution with an on-premises deployment option that monitors the security of Active Directory in real time. The solution enables users to find and fix existing weaknesses with dynamic threat scoring, complexity ratings and recommended actions. Alsid continuously and non-disruptively discovers new attack pathways and detects ongoing attacks in real time, recommending remediations without the need to deploy agents or leverage privileged accounts.
Exploiting user privileges via Active Directory is a favorite and predictable tactic in many sophisticated compromises and common hacks. This risk has never been more acute than it is today, with so many people working remotely and often using personal devices to connect to corporate systems, with Active Directory playing a critical role in managed single sign on. For this reason, organizations are increasingly focusing on securing accounts — employees, service contractors, temporary workers, systems accounts and others — and their access to and permissions across systems as strategic to their cybersecurity posture. Understanding account access to systems and how those cascade across compute environments is a strategic and important complement to vulnerability management and systems hygiene and is increasingly imperative to managing risk holistically, especially in complex cloud and hybrid environments.
Alsid was founded in 2016 by two former incident responders from the French National Cybersecurity Agency (ANSSI), Emmanuel Gras and Luc Delsalle. Alsid’s founders will join Tenable in senior leadership roles focused on continuing to develop innovative solutions to Active Directory risk and security assessment and expanding into new markets globally.
Under the terms of the agreement, Tenable will acquire Alsid for a total purchase price of $98 million in cash, subject to customary purchase price adjustments. The acquisition is expected to close early in the second quarter of 2021, subject to regulatory approvals and the satisfaction of customary closing conditions.
Alsid’s financial results in 2021 are expected to contribute approximately one percentage point of growth to revenue and calculated current billings and increase incremental operating expenses in the range of $15-20 million, while free cash flow is expected to be impacted to a lesser extent and be accretive some time in 2022. We expect to incur $3-4 million in acquisition-related expenses, including transaction expenses over the course of the first and second quarters in 2021. Consistent with prior practice, we plan to exclude these costs from our non-GAAP results.
