Fix Broken Links & Harden Site

I have discovered well over ten broken links scattered throughout my website, hurting both user experience and SEO. I need a systematic crawl, confirmation of every faulty URL, and then permanent, search-engine-friendly fixes—whether that means updating paths, creating 301 redirects, or replacing removed resources.

While the immediate pain point is functionality, I also want to use this opportunity to tighten overall site security. I haven’t isolated specific threats yet, but I’d like a full scan and clear, prioritized recommendations so I can stay ahead of malware, unauthorized access, and other common risks.

Please include the following in your proposal:

• A brief outline of your link-audit process (e.g., Screaming Frog, Search Console, custom scripts).
• The security-assessment tools you prefer and the type of report I will receive.
• An estimated turnaround time to fix more than ten links and produce the security findings.

Acceptance criteria: every broken link tested and resolved, a before/after list delivered in CSV or Google Sheet, and a concise security report highlighting discovered vulnerabilities with suggested next steps.
