With an increase in threats to a business’ network, it is very important to secure it. A business can choose to have their own security team, or choose to outsource that security to “managed service” companies. Cnet is reporting that On Tuesday, the carrier announced several managed services for midsize companies, including intrusion protection, vulnerability scanning, virus and spam protection, and new managed firewalls. MCI CEO Michael Capellas told reporters last week, when the company emerged from bankruptcy protection, that MCI would be targeting security services. The focus on security comes as MCI faces stiff competition and falling prices in its long distance consumer business. The situation has put pressure on long distance carriers to find new sources of revenue.
