- Ensure compliance with security, regulatory, and operational standards, including clearance readiness for Five Eyes partners
- Partner with Legal and Finance to resolve regulatory HR matters

Our take
As the shift to virtual working environments and remote working continues, internal collaboration tools have never been in higher demand, Mattermost's key product is well-positioned to meet this surge in demand: it is essentially a collaboration platform which offers secure messaging across web, desktop and native mobile devices.
Mattermost runs as a server install that can be accessed remotely or locked down so that it only runs internally. That’s a major benefit for any company that needs to comply with industry regulations, such as hospitals, law firms and government agencies. This is also what sets Mattermost apart from other collaboration platforms like Slack, Zoom and Microsoft Teams.
The company powers messaging and collaboration for a host of businesses including Samsung, Daimler, SAP and Cigna. With solid foundations and a big prospective customer base, Mattermost is well-set to achieve big things as it continues to launch new features for its expanding client base.
