# Update to Security Header and Compatible Browser Versions

## Symptom

HTTP security headers provide extra security for your web applications by restricting the actions that the browser and server allow once your site is running. SAP Ariba solutions add a number of default security headers to all requests to your site. These security headers are added to the site every time a user renders your web application in any standard browser.

The following secruity headers are now enabled as part of this feature:

- Strict-Transport-Security
- X-Content-Type-Options
- Permissions Policy
- Referrer-Policy

After updating the security header, users might notice better security and improved compatibility with different browsers.

However, if user is using the older version, they might face problems with page navigation, loading pages, and displaying content.

## Environment

Ariba Applications and SAP Business Network

## Cause

If you do not upgrade to a supported browser version, you may not be able to access some pages, experience visual or functional problems, and lose the ability to complete some business processes.

## Resolution

As of **March 2, 2024**, the SAP Ariba Applications and SAP Business Network will only support the following browser versions:

- Google Chrome (88 or above)
- Microsoft Edge (88 or above)
- Mozilla Firefox (87 or above)
- Apple Safari (15 or above)
- Mobile Safari on iPad (15 or above)

Also, SAP Ariba will not accept bug fix or enhancement requests associated with older browser versions.
