Most small businesses in San Jose and the South Bay never check whether their email domain can be spoofed, or whether their website is missing basic browser security headers — until something goes wrong. This scan gives you the same information an attacker (or your insurance carrier) would look for, in plain English, without any technical background required.
SPF, DKIM, and DMARC control whether someone can send a phishing email that looks like it came from your domain — a common way attackers target law firms, dental offices, and accounting firms across Silicon Valley. SSL and HTTP security headers control how well your website protects visitors' data in transit and whether it's exposed to common browser-based attacks.
This is a passive, read-only check — the same kind of information any browser or mail server already sees. It doesn't scan ports, probe for vulnerabilities, or touch anything on your server. For a deeper look, including what's actually configured on your network and endpoints, our cybersecurity services cover the full picture, or start with a free IT assessment.
Yes. Enter your domain and get instant results for SPF, DKIM, DMARC, SSL, HTTP security headers, and DNS configuration — no signup required to see your results.
No. This is a passive check — it only reads publicly available DNS records, your SSL certificate, and HTTP response headers, the same information any browser or mail server already sees. It does not scan ports, probe for vulnerabilities, or attempt any kind of exploit.
These three records tell email providers whether a message claiming to be from your domain is legitimate. Without them, it's easier for attackers to spoof your domain in phishing emails sent to your clients, vendors, or staff.
Most of these issues are quick fixes once you know what's missing. Request a free IT assessment and LineSight Digital will walk through the specific fixes for your domain and hosting setup.
