Otta's take

Xav Kearney

CTO of Otta

Proofpoint is a cybersecurity and compliance company addressing the ever-evolving risks that organizations face in the digital landscape. Recognizing the challenges posed by a wide range of threats, it has introduced a number of solutions that provide visibility, flexibility, and depth to detect and disrupt sophisticated adversaries across the attack chain.

One of Proofpoint's advancements is the Aegis Platform, an AI/ML-powered cloud-based threat protection system that specifically targets email fraud, ransomware, credential phishing, and other advanced attacks. What sets it apart is its industry-first Large Language Model (LLM)-based pre-delivery threat detection, which identifies social engineering attacks before they can reach the recipient's inbox.

To further enhance its capabilities, Proofpoint recently acquired Tessian, a British startup specializing in cloud email security software. This acquisition will enable it to better identify and mitigate risky user behavior. If Proofpoint continues to expand its offerings, it could be poised to play a pivotal role in safeguarding organizations against cybersecurity risks, ultimately contributing to a safer and more secure digital environment.
