Juniper NetScreen [EOL] Reviews Summary
Author infoRatingReview Summary
Network and Security Engineer4.0I found this solution easy to use with good stability. My main issues were with search functions and scalability due to object limits, requiring rule rationalization. Technical support was good, and pricing was acceptable.
Product Line Manager at a tech services company with 51-200 employees5.0I recommend this product for its reliable stability, valuable features like VPN and routing, and overall good support, despite some initial setup complexity and areas for Next-Gen Firewall and logging improvements.
Security Analyst - ISO 27001 at a tech services company with 1,001-5,000 employeesI consider Juniper NetScreen a straightforward, user-friendly firewall, easy to deploy for mid-size to enterprise needs, offering reasonable security. However, it's EOL soon, and I've experienced some central management and remote access issues.
