Fortinet’s FortiGate line is the company’s Firewall/NGFW offering, covering stateful firewalling, application control, IPS, web filtering, SSL/TLS inspection, and threat-intelligence-backed blocking. It is widely deployed from branch and edge sites to enterprise perimeter and segmentation use cases, with hardware, virtual, and cloud form factors managed through the same Fortinet policy stack. Buyers typically choose it when they need firewall enforcement plus inline inspection and VPN capability in one appliance, especially in environments that already use FortiGuard threat feeds or the Fortinet Security Fabric. Adjacent products include SD-WAN and ZTNA, but those are not the core scope here.
Greenbone Enterprise Appliance (also known as OpenVAS, Open Vulnerability Assessment System, Greenbone's open-source scanner) provides professional vulnerability management built on the OpenVAS framework. It offers robust scanning, asset management, and reporting capabilities, with both an enterprise appliance for organizations seeking reliable, scalable security assessments and an open-source edition often used for cost-effective vulnerability assessment, penetration testing support, and educational purposes.
NSFOCUS offers a broad portfolio of security products including DDoS protection, Web Application and API Protection (WAAP), and an Integrated Security Operations Platform. The company serves large enterprises and telcos with high-capacity mitigation hardware and cloud-based threat intelligence. It provides massive-scale DDoS scrubbing and continuous threat exposure management (CTEM) capabilities.
PPalo Alto Networks is a major vendor in the Firewall / NGFW market, best known for PAN-OS-based next-generation firewalls and Cloud NGFW. Its firewalls combine application-aware policy, user-based controls, and threat prevention to inspect traffic, including encrypted sessions, and block known and unknown threats. It fits enterprises that need granular segmentation, internet edge protection, and consistent policy across physical and cloud deployments. Adjacent offerings exist, but the core firewall line remains centered on network traffic control, inspection, and prevention.
Sophos defeats cyberattacks with an adaptive AI-native open platform and unmatched security expertise.
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.
What is Network Security software?
Compare and discover the best Network Security software and tools for your team. Find the right solution for your needs. With 8 network security tools listed on Picari, you can compare features, pricing models, and real user experiences side-by-side, without speaking to a single sales rep until you're ready.
Who needs network security tools?
Network Security software is typically adopted by teams that have outgrown manual processes and need repeatable, scalable workflows. You'll get the most value if:
- Your team spends more than 5 hours/week on tasks that could be automated
- You're scaling past 10 team members and need consistent processes
- You need better visibility into performance metrics and ROI
- Your current tools don't integrate well with the rest of your stack
Buying criteria checklist for network security
Before committing to a network security platform, run through this evaluation checklist:
Common mistakes when evaluating network security tools
- 1.Buying based on demos alone. A polished demo doesn't reveal how the tool handles your actual data and workflows. Always run a proof-of-concept.
- 2.Ignoring total cost of ownership. The sticker price is rarely the full cost, factor in implementation, training, integrations, and potential add-on fees.
- 3.Not involving end users in the evaluation. The people who'll use the tool daily should have a say. Top-down purchases often lead to low adoption.
- 4.Comparing too many tools at once. Shortlist 2–3 finalists max. Evaluating 5+ tools in parallel leads to decision fatigue and delayed timelines.
