GC Solar and SEG-T have announced the launch of a new Security Email Gateway solution aimed at strengthening corporate email protection through advanced multi-agent AI filtering. The initiative is led by co-founder of Secure-T, Khariton Nikishkin, with support from GC Solar, and directly addresses the rapid growth of sophisticated phishing campaigns that increasingly rely on pre-built toolkits and artificial intelligence.
Modern phishing operations now combine ready-made components such as management panels, distribution infrastructure, anti-bot mechanisms, and one-time code interception modules. Attackers further enhance these campaigns by using AI to generate more convincing messages and scale their reach. SEG-T is being developed to go beyond conventional technical analysis by evaluating the semantic content of emails, including tone, signs of psychological manipulation, attempts to establish trust, create fear, or pressure recipients into immediate action.
The gateway will automatically block messages containing potentially dangerous elements such as links, archives, PDF files, executable files, SVG images, and other attachments that could carry malicious content. Developers have decided against including a built-in sandbox, arguing that the majority of current attacks rely on social engineering rather than malware code. However, the solution will allow integration with external sandboxes for high-risk attachments when needed.
SEG-T is designed to work seamlessly with other GC Solar products, including Solar webProxy for traffic inspection and Solar Dozor for monitoring the transmission of sensitive personal data such as INN, SNILS, passport details, and bank card numbers.
The platform will be available in multiple deployment models: cloud, on-premises networks, and Kubernetes environments. According to the developers, initial setup and commissioning of SEG-T should take approximately 15 minutes. GC Solar owns 49% of the project and previously increased its stake in Secure-T to a controlling interest. The new product continues the company’s strategic focus on defending against phishing, spam, malicious mailings, and targeted attacks on corporate email systems.
