Controls an Cross-Site Scripting (XSS) filters built into the majority of web browsers. The filter is usually turned on by default anyway, but requirement to set the header to
1 became part of canonical set of "secure" HTTP headers. Over time, vulnerabilities in the "sanitizing" mode filter were found, so
1; mode=block became the recommended value. Some companies decided that they don't really need a browser-side XSS filter to mess with their web services which are XSS-free anyway and they became consciously disabling the XSS filter by setting the header to

Content Security Policy is used by a web server to declare a list of trusted content types (images, scripts, media etc) and origins from which they can be safely loaded as intended by the website authors. The
Content-Security-Policy-Report-Only header instruct the browser to enable CSP in enforcement mode.

Announces a list of X.509 certificate hashes that are allowed to appear in the website's TLS certification path (HTTP Public Key Pinning or HPKP). This prevents malicious proxy servers from transparently replacing the public certificates with their own and wiretapping the TLS connection of the unsuspecting user. This header sets HPKP in report-only mode.Read more...

HTTP Strict Transport Security is enabled+2
HTTP Strict Transport Security (HSTS) is an opt-in security enhancement that is specified by a web application through the use of a special response header.Read more...
Fuzzy content type guessing is disabled+1
A non-standard but widely accepted header introduced originally by Microsoft to disable "content sniffing" or heuristic content type discovery in absence or mismatch of a proper HTTP
Content-Type declaration, which led to a number of web attacks. In general, presence of the header with its only defined value of
nosniff is considered as part of a properly secured HTTP response.
The header sets permissive AJAX access by using wildcard origin
*. It may be OK if the website is a publicly accessible REST API but otherwise it should be not present at all
XmlHttpRequest from a website that is not in the same origin, which is a precaution against various types of data stealing attacks. The target server has to explicitly allow the origin domain using the
Access-Control-Allow-Origin (ACAO) header, or it may allow all origins to access it using a wildcard
*. The latter however creates a potential security issue if the website in question is transactional and processing sensitive data, so the wildcard should be only used on websites consciously offering public APIs.
Transport Layer Security (TLS) is enabled+2
