Symantec acquired two companies — Javelin Networks and Appthority — to bolster its endpoint security business and its mobile and enterprise security credentials. Terms of both deals were not disclosed.

Both of the companies, including their teams and technology, will become a part of Symantec’s endpoint security business.

Symantec’s endpoint security stack is built in a single-agent architecture. It is one of four parts of Symantec’s Integrated Cyber Defense platform, which also includes network, cloud security, and newer born-in-the-cloud security technologies.

Javelin Networks is a privately held security software company. Its technology defends against Active Directory (AD)-based attacks. AD is open to any domain-connected user, which makes identities and resources on a corporate network vulnerable to attack. According to Symantec, Microsoft AD services are the most widely used AD services and are becoming an increasingly popular target.

Javelins’ software technology is built to protect AD and commonly used domain resources from the endpoint. These resources include domain controllers, identities, and credentials. It works by containing attackers after an endpoint is comprised so that they can’t make it to the domain and access the AD to attack other network assets.

The second company Symantec is acquiring is privately held Appthority. Appthority’s technology offers mobile application security analysis, which enables users to analyze mobile apps for malicious capabilities and vulnerabilities to data loss and other privacy-invasive actions.

This technology will be integrated with that of another acquisition, which Symantec made last year. In July 2017 Symantec bought Skycure, a mobile threat defense company, which it used to launch its Endpoint Protection Mobile platform. Appthority’s capabilities will be rolled into this platform, adding to the spectrum of endpoints and operating systems it protects.

Symantec has been making a number of updates to its security portfolio in order to boost its credibility and clout with enterprise customers. In October, the company rolled out significant cloud security updates. This included protections for workloads running on Amazon Web Services (AWS) and Microsoft Azure, bringing its cloud access security broker (CASB) visibility to mobile apps, and it began offering its security products and services as a managed service.

In its second quarter earnings call with investors, Symantec CEO Gregory Clark spoke to the edge that Symantec has within the competitive endpoint security market. “We are very effective in the enterprise context around protecting against malware in the endpoint, whether it be through traditional signature-based detection and prevention technologies as well as our AI [artificial intelligence],” said Clark, according to the Seeking Alpha transcript of the call. He also boasted “good wins” and “taking accounts away from others” in the endpoint segment.
