Add the header with a max-age of at least 1 year. - **[WARNING]** X-Content-Type-Options header is missing — This header prevents MIME-type sniffing, which can lead to XSS attacks. Set it to 'nosniff'. - **[WARNING]** X-Frame-Options header is missing — This header prevents clickjacking by controlling who can embed your page in a frame. Set it to DENY or SAMEORIGIN. - **[WARNING]** Referrer-Policy header is missing — Controls how much referrer information is sent with requests.
