Their suite of security solutions is designed to prevent specific threats, safeguard sensitive data, and enhance user resilience against cyberattacks.

With Proofpoint’s advanced protection, businesses can operate with confidence and peace of mind in today’s ever-evolving threat landscape.

AI-Based Email Security

Proofpoint is a leading provider of security and compliance solutions that prioritize people’s safety and privacy.

Its cutting-edge technology is designed to help businesses of all types mitigate their most crucial risks across various platforms, including email, cloud, social media, and the web.

With Proofpoint’s powerful tools, companies can ensure the highest level of security and compliance without compromising their users’ experience.

The ability of AI-powered surveillance to identify risks intended for individuals, such as phishing emails and assaults on vendors, and to prevent the loss of data caused by either intentional or unintentional actions has been outstanding.

According to the report, in 2022, 65% of all data loss events happened through email, and almost two-thirds of businesses lost data or had it stolen because an employee made a mistake on email. 

“Far too often, human errors with email lead to organizations putting their and their customer’s data at risk, breaching industry and data protection regulations, and losing mission-critical intellectual property,” said Darren Lee, executive vice president and general manager.

Tessian’s AI-powered email security platform is set to enhance Proofpoint’s email data loss prevention (DLP) service by effectively mitigating both accidental data loss and malicious insiders.

The integration of Microsoft 365 and Google Workspace into Tessian’s platform ensures a seamless implementation that enables organizations to maximize their email security. Some instances of Tesseracts include:

  • Protects sensitive data, helps customers achieve regulatory compliance and confidentiality agreements, and avoids the risk of reputational damage by eliminating misdirected emails and mis-attached files.
  • Automatically protects against data exfiltration and safeguards intellectual property without predefined rules or deny lists.
  • Context-aware, AI-based email defense that detects and prevents the full spectrum of email attacks while providing end users with in-the-moment contextual warning banners to help them decide whether an email is safe.
