// About the founder
Watched by software. Answered for by a person.
Guardian Monitor is a product of Forestal Security — a founder-led security practice built for small businesses that need senior-level protection without big-firm complexity.
I'm Edith Forestal. I've spent over a decade building and running technology companies — and today I develop AI-driven security tools used in more than a thousand analyses. My work spans vulnerability assessment, cloud and identity security, ethical hacking, and security automation, backed by a master's in cybersecurity and some of the industry's most rigorous certifications. When Guardian Monitor watches your domain, it's applying the same checks I use to defend high-stakes, heavily audited systems every day.
This isn't a faceless SaaS. The alerts are tuned by me, the monthly digests are built by me, and if something serious surfaces, I'm the one who understands what it means.

Questions
Common questions.
Do you need access to my systems or accounts?
Never. Every check Guardian Monitor runs is based on publicly visible information — your domain name is all we need. We do not access your Microsoft tenant, your hosting account, your DNS provider, or any internal system. Everything we monitor is observable from the public internet.
How quickly will I be alerted if something is found?
Certificate monitoring runs every 15 minutes — if a criminal registers a lookalike domain and gets a certificate for it, you'll know within the hour. Dark web alerts are triggered as soon as new breach data surfaces. SSL expiry alerts are sent at 60, 30, and 7 days before expiry.
What is the free scan and what does it check?
The free scan is a one-time snapshot of your domain's public security posture — it runs live checks against your real DNS records and web server: email authentication (SPF, DKIM, DMARC), TLS/SSL certificate validity, and DNSSEC. It does not include continuous monitoring, dark web scanning, or certificate transparency log surveillance — those require a Guardian Monitor subscription.
Can I cancel at any time?
Yes. There are no contracts and no cancellation fees. Cancel from your account dashboard and your monitoring stops at the end of the billing period. No questions, no retention calls.
