Cisco IOS SSL VPN vs OpenVPN Access Server comparison

Cisco IOS SSL VPN and OpenVPN Access Server both compete in the secure VPN solutions market, addressing different business needs. Cisco's enterprise-grade features and strong security support put it at an advantage for businesses seeking comprehensive support, while OpenVPN's cost-effectiveness and open-source nature are better suited for budget-conscious users looking for flexibility.

Features: Cisco IOS SSL VPN provides strong encryption, versatile remote access configuration, and customizable web portals. It is known for its stability and the simplified configuration offered by its ASA devices. OpenVPN Access Server, on the other hand, is valued for its scalability, ease of integration with different platforms, and cost-effectiveness. It supports strong encryption and basic VPN functionalities, making it highly configurable for various needs.

Room for Improvement: Cisco IOS SSL VPN could improve its user mapping, access control features, and firewall rule configuration, with a need for better Java integration. Its high costs are also a barrier for smaller businesses. OpenVPN Access Server lacks the extensive protocol support that Cisco offers and could enhance its security features and configuration ease, particularly for non-technical users. There is room for improvement in its performance under heavy load.

Ease of Deployment and Customer Service: Cisco IOS SSL VPN typically involves complex deployment requiring on-premises infrastructure and reputable technical support, often through local partners. OpenVPN Access Server offers more deployment flexibility, including public, private, and hybrid clouds. Its open-source nature and ease of use reduce the need for extensive technical support, though assistance is available for a fee.

Pricing and ROI: Cisco IOS SSL VPN is priced based on user licenses and requires annual subscriptions, with high costs offset by strong security and support, yielding good ROI for enterprises. OpenVPN Access Server is free and open-source, providing significant cost savings and a strong ROI for cost-conscious businesses, especially those that prioritize pricing without sacrificing essential VPN features.
