jQuery & IE 8-11 Continued Support

We support compatibility scans for IE versions 8-11.

Shipping unsupported libraries puts you at risk.

Do you have FedRAMP, PCI, HIPAA, or other compliance concerns?

Our clients breeze past such concerns by having Bootstrap NES – a fully supported and secured library.


Switch in less than 5 minutes
Switching from Bootstrap 3 or 4 to Bootstrap NES is done in three easy steps:
Sign up for Bootstrap NES
Configure NPM to use Bootstrap NES
NPM Install and run your tests

After sign up, setup and installation, you should expect to install updates regularly.
These updates will contain fixes for security issues and browser compatibility changes.

The Cost of Inaction

Discover the consequences of staying on an unsupported Bootstrap version.
Vulnerable to Cyberthreats

When Bootstrap reached the end of life, security updates stopped.

In 2017, Equifax was still using a deprecated version of Apache Struts web application framework. Hackers gained access to names, Social Security numbers, birthdates, addresses, and other sensitive information of millions of people. That vulnerability had been patched in a newer version of the Struts framework. But Equifax failed to upgrade until it was too late.

Bootstrap NES means ongoing security scans and vulnerability fixes. If a vulnerability is found, our team of Bootstrap core contributors will fix, test, and release a security patch within 14 days of vulnerability discovery.

Legal Liability

Are you bound by SLAs that mandate the use of supported software? Non-compliance can invite legal consequences, potentially leading to costly litigation. Ensure your digital operations remain within the bounds of the law.

Bootstrap NES is fully supported, which means continued compliance with your SLA.
