The Websites may include links to sites operated by third parties. This does not mean that KLA endorses these sites, nor are we responsible for their content or policies. Third party sites are governed by their own privacy policies. You should familiarize yourself with the privacy policy of other sites you visit as it will govern any information you provide through that site.


KLA has implemented measures designed to secure your personal information from accidental loss or unauthorized access, use, alteration and disclosure. However, the transmission of information via the Internet is not completely secure. The Websites use HTTP Secure (“HTTPS”) for secure communications. The Websites use Transport Layer Security (“TLS”) to protect information collected through the Websites. In addition, the Company restricts access to your personal information. Only employees who need the personal information to perform a specific job (for example, a customer service representative) are granted access to personal information.

Although the Company uses efforts to protect your personal information, we cannot guarantee the security of the information transmitted through the Websites.
