Corporate Messaging: Where To Position The Security Solution?

In the era of hybrid work , the decentralization of exchanges, collaborative work and ubiquitous cloud tools, it is crucial to protect all exchanges that pass through the company.

Indeed, the points of contact are very numerous and the control must be rethought in the face of work at home, in third places (coworking space, at a client’s, in a café, etc.), or on the move. Not to mention that the use of personal solutions is thus on the increase.

When a customer communicates by WhatsApp, sends files by Slack or uses document sharing via WeTransfer, for example, the risks are numerous, because these tools are not necessarily part of the native technological solutions monitored by the company. Not to mention the trend of BYOD (Bring your own Device) which adds an additional challenge.

Faced with these challenges, there are now new security solutions for messaging that connect directly to Cloud messaging, which avoids going through the legacy mail relay. Security solutions themselves present in the cloud and which are very simple and quick to activate.

The content of the message will be analyzed by anti-spam modules based on email signatures that have been flagged as spam.

The solution can very well operate a lexical analysis in order to identify specific keywords, turns of phrase or links pointing to sites recognized as being dangerous.

Sandbox

The sandbox system is an innovative security feature . Its approach is different from that of an antivirus which works according to a periodically updated knowledge base.

The sandbox will run a dubious attachment in a secure environment to analyze its behavior. If the threat is proven, the information will be sent back to the element that submitted the analysis to it and will make the decision to place it in quarantine or simply destroy it.

This review takes time, but greatly secures corporate mailboxes . Sandbox analysis proves to be a protection that is all the more essential and useful as it can be queried at any time by the firewall , proxy or mail relay and thus share its knowledge base.
