What to fix

Add Strict-Transport-Security
Header: Strict-Transport-Security: max-age=31536000; includeSubDomains
Add a Content-Security-Policy
Limits which scripts can run, and is the main defense against XSS. Start with Content-Security-Policy-Report-Only to test.
Mark cookies Secure and HttpOnly
At least one cookie is sent without these flags, exposing it to interception or scripts.
Publish an SPF record
A DNS TXT record listing who may send email for this domain, which prevents spoofing.
Publish a DMARC record
A TXT record at _dmarc.<domain>; start with v=DMARC1; p=none; to monitor.
