Microsoft has sounded the death knell for its Edge browser's Internet Explorer (IE) Mode, announcing that support will officially cease by 2029. If your business relies on legacy web applications that require this mode, it's time to start planning. Waiting until the last minute could expose your company to significant risks, including security vulnerabilities and operational disruptions.
The Timeline and Immediate Implications
The announcement from Microsoft puts a firm 2029 deadline on the use of IE Mode in Edge. This timeline may seem distant, but transitioning from legacy systems to modern web solutions is not a quick fix. For businesses still dependent on IE Mode, the clock is ticking to evaluate and update their web applications accordingly. Microsoft has been gradually phasing out its support for older technologies, and this is part of that broader strategy.
Who is Vulnerable?
Any UK SME currently using legacy web applications that depend on IE Mode is at risk. These are typically older systems that haven't been updated to work with modern browsers. To check if you're exposed, review the web applications you currently use. If they require IE Mode, you'll need to take action.
Practical Steps to Take
- Audit Your Applications: Identify which applications rely on IE Mode.
- Consult with Developers: Assess the feasibility of updating or replacing legacy applications.
- Plan a Transition: Develop a timeline for moving to modern solutions, considering both cost and resources.
- Test New Solutions: Before fully transitioning, run pilot tests to ensure compatibility and functionality.
Common Missteps
A pattern we see on most tenants we take on is a reluctance to address legacy systems until it's almost too late. Many businesses underestimate the time and resources required to transition away from outdated technologies. Delaying these updates can lead to rushed decisions and potentially costly mistakes.
Regulatory Considerations
The end of support for IE Mode could have regulatory implications, particularly if your business handles sensitive data. Non-compliance with data protection regulations such as GDPR due to insecure legacy systems could result in fines and reputational damage.
