TAC LinkGuard

Your links are only as safe as the last time you checked them.

You are about to send a newsletter to 10,000 people. You have got 47 links in it. Did any of them go bad since you saved them? Is that affiliate link still clean? Did one of your sources quietly get compromised?

One bad link can get your sending domain blacklisted. Gmail and Outlook flag senders who link to known malware or phishing sites. Once you are blacklisted, your deliverability tanks and getting off those lists takes weeks. Your reputation with 10,000 subscribers, gone because of one link you did not check.

What TAC LinkGuard does:

Scans any number of URLs against three industry-standard threat intelligence sources and gives you a clear verdict for each one: CLEAN, WARNING, or MALWARE.

What you get per URL:

• Server location (country + city)
• TLS version
• Domain registration age
• Redirect chain analysis
• URLhaus threat match (trusted by Spamhaus, VirusTotal, and Cloudflare)
• Clear threat verdict with reasoning

What makes it different:

• No API key needed
• No credits, no subscriptions, no recurring costs
• Scan 1 URL or 1,000 in one go
• Smart batch throttling built in
• Powered by the same threat intelligence feeds used by enterprise security teams

How your agent uses it:

• "Scan all the links in this email before I click anything" — Agent extracts every URL, runs LinkGuard, flags the sketchy ones
• "Check every outbound link on my latest blog post" — Agent pulls your page, scans all links, tells you which are broken or flagged
• "Here is a list of 200 affiliate links. Which ones are still safe?" — Batch-scans all 200 in under a minute
• "I got a job offer with 3 links. Are they legit?" — Checks domain age, server location, malware status before you click
• "Monitor the links dropped in my Discord server today" — Collects shared URLs, runs a safety check, alerts you
