AI-native data loss prevention and insider threat detection platform that discovers, classifies and protects sensitive data across SaaS, GenAI, endpoint and email. Detects unauthorized uploads, shadow AI usage, exfiltration and policy violations in real-time using ML-based classifiers, replacing legacy DLP and UEBA with autonomous behavioral monitoring and prevention before data loss happens.

Perimeter 81, acquired by Check Point in 2023 and rebranded as Harmony SASE, delivers a cloud-native Secure Access Service Edge (SASE) platform consolidating networking, Zero Trust Network Access (ZTNA), secure web gateway (SWG), and cloud access security broker (CASB) for remote and hybrid workforces. It replaces legacy VPNs with software-defined perimeters, IPSEC tunnels, and WireGuard connectors to private applications, enforcing granular policies based on identity, device posture, geo-location, and time. Best suited for mid-sized enterprises migrating to cloud environments seeking unified SSE without hardware deployments.

Proofpoint is a human-centric cybersecurity platform focused on protecting organizations from email-based and identity-driven attacks such as phishing, business email compromise (BEC), and social engineering. It secures inbound and outbound communications using advanced threat detection, AI-driven impersonation analysis, URL and attachment sandboxing, and behavioral risk signals. Beyond email protection, it extends into data loss prevention (DLP), insider threat detection, and security awareness training to reduce human risk across the organization. The platform integrates across email, cloud applications, and collaboration tools to protect sensitive data and stop attacks targeting users.

Trellix Helix is a SaaS security operations platform that unifies SIEM, SOAR, and threat intelligence, integrating over 600 Trellix and third-party tools for multi-vector threat detection and response. It augments existing SIEMs with analytics, behavioral analysis, and workflow automation, enabling correlated investigations across endpoints, networks, and cloud environments. Best suited for enterprises seeking XDR capabilities without replacing legacy SIEMs, it leverages Trellix's global threat intelligence for contextual IOCs and TTP-based rules, streamlining alert triage and containment.

Trend Micro offers integrated Data Loss Prevention (DLP) functionality embedded within its broader endpoint security and email security platforms. The iDLP module provides lightweight agent-based monitoring across endpoints, email, USB devices, and web channels without requiring dedicated hardware. Trend Micro positions DLP as a cost-effective alternative to standalone enterprise solutions, leveraging pre-built regional and industry-specific policy templates. Best suited for organizations already invested in Trend Micro's endpoint protection or email security infrastructure seeking consolidated data protection without additional management overhead.

Zscaler provides a cloud-native Zero Trust Exchange platform with over 150 global POPs, processing 200 billion+ daily transactions for secure user-to-application connectivity. It delivers Zscaler Internet Access (ZIA) as a security service edge (SSE) with secure web gateway (SWG), full SSL inspection, and Zscaler Private Access (ZPA) for zero trust network access (ZTNA) replacing VPNs. Backed by machine learning from massive scale, it offers 200,000+ daily security updates. Best for distributed enterprises needing low-latency protection for remote users, SaaS, and private apps without legacy hardware.
