Why is Updating your Cisco Router’s IOS Firmware Important?

Security, Security, Security!!!  Have your heard about Ransomware?  How about the WannaCry Ransomware attack?  Most companies do a decent job of keeping their computer’s operating systems up to date, but when it comes to routers and peripherals not so much.  Hackers exploit vulnerabilities in routers as well.  New Firmware could include bug fixes, feature enhancements and security fixes and improvements. These updates are as important as updates to your computer’s operating system.  Unfortunately a lot of companies just don’t do it.  Using OSG’s managed services you can be sure that your Cisco Router’s IOS Firmware will always be up to date. 

A reliable network firewall helps protect your business from unauthorized access, while permitting legitimate traffic. It’s an essential component of any size network. As your business evolves and adapts to mobility, cloud, and the rising threat landscape, you need to see the users, applications, content, devices, and threats on your network and what they are doing. You need to protect your business and network from multi-vector threats across the entire attack continuum.

Cisco offers firewalls to match a variety of needs.

  • For high-speed, data center environments, Cisco ASA 5585-X Adaptive Security Appliances and Cisco Catalyst 6500 Series ASA Services Modules deliver multiscale performance for maximum connections per second with the lowest overhead.

  • For edge and campus environments, we offer the Cisco ASA 5525-X, ASA 5545-X, and ASA 5555-X, as well as routers with integrated Cisco IOS Firewall.


For small or branch office environments, get integrated firewall and security in the Cisco Integrated Services Router Generation 2 and in the Cisco ASA 5505, ASA 5506-X, ASA 5506W-X, ASA 5508-X, ASA 5516-X, ASA 5512-X, and ASA 5515-X appliances.

  • A ruggedized appliance (5506H-X) designed for industrial control systems and critical infrastructure applications with harsh environmental conditions.

  • For virtualized environments, choose the Cisco Adaptive Security Virtual Appliance (ASAv) and Cisco ASA 100V Cloud Firewall.


The needs of many organizations go well beyond traditional threat defense. That’s why we also offer VPN technology, intrusion prevention, content security,unified communications security, and integrated threat defense in many of our firewall solutions, including the ASA 5505 and ASA 5500-X Series Next-Generation Firewalls.
