5 secure messaging tools for useful out-of-band management

‍

IBM reports that effective communication during cyber attacks and IT incidents can significantly reduce resolution time and enhance incident management. For instance, companies can use out-of-band management (OOBM) solutions to access a secure, dedicated network infrastructure for seamless collaboration.

Secure collaboration tools focused on OOBM are necessary to help employees, customers, and leaders stay on the same page. Unfortunately, when primary networks fail, relying on inadequate and compromised platforms can exacerbate such cybersecurity incidents. 

If you want to ensure uninterrupted and secure communication during a cyber crisis, in this blog post, we’ll discuss 5 out-of-band management tools that’ll help rapid incident responses and coordination.

Why are secure messaging tools critical for out-of-band management?

Reports suggest that the out-of-band authentication industry reached USD 1.5 billion in 2024. Between 2025 and 2033, this market is expected to have an 18.7% CAGR and reach USD 7.5 billion.

This sector will experience such growth due to the escalating cyberattacks and data breach threats. 

Statista highlighted that 38% of CISOs considered malware, followed by DDoS attacks, a significant risk to their enterprise’s cybersecurity. 

As a result, robust security and stringent compliance standards in messaging tools become a necessity. The right collaboration platforms are critical for out-of-band management because they:

• Provide independent communication channels during cyberattacks for a secure and effective incident response, reducing the risk of interception.
• Enable seamless coordination and allow real-time updates between leadership, IT, and support teams. This ensures strategic decision-making and maintains operational effectiveness during data breaches.
• Help minimize reliance on in-band communication systems and ensure continuous incident response capabilities. Out-of-band management tools facilitate crisis management and rapid information sharing.

According to Marsh, an encrypted and secure out-of-band management platform can streamline efficiency, support organizational operations, and protect essential information.
