Threat Intelligence

Email threats are becoming more sophisticated every year. Worryingly, a significant portion of email enters a user's inbox through your Secure Email Gateway (SEG). Social engineering attacks are increasingly targeting your high-risk users. According to the 2023 Verizon Data Breach Survey, email is the biggest cause of data breaches. ArmorBlox researchers recently reported that the 56% attack bypassed your traditional security filters. The result? Traditional email security allowed these digital time bombs to slip into users' inboxes.

Choose PhishER Plus for timely response to evolving cyber threats, providing you with advanced protection at all times.
