// About us · Made in Guatemala

Born in Guatemala. Vigilant by nature.

Vigilant Core was founded by two Guatemalan engineers with a shared conviction: identifying a security risk should be the beginning of a solution, not the beginning of more uncertainty.

// Our inspiration

“Observe carefully, recognize meaningful signals, and act with purpose.”

We found our inspiration in the kingfisher. Its watchful presence and precise movements reflect our approach to cybersecurity: observe carefully, recognize meaningful signals, and act with purpose.

// Our story

We bring that philosophy to the digital environment through agentic AI—AI agents that coordinate discovery, analysis, and prioritization across an organization’s authorized assets. Vigilant Core examines the attack surface to identify exposures, vulnerabilities, and configurations that need attention.

Detection, however, is only part of the work. We turn findings into remediation playbooks: practical guides explaining what needs attention, why it matters, and which steps to follow to address it and verify the outcome. This helps teams move from technical alerts to informed decisions.

Vigilant Core is in product validation. The examples on this page are illustrative and do not represent customers or active operations.

// From instinct to method

Three kingfisher instincts, applied to your attack surface.

  1. 01

    Watches from the branch

    Observe

    AI agents coordinate discovery across each organization’s authorized assets: domains, subdomains, exposed services, and certificates.

    discover → authorized assets

  2. 02

    Spots movement beneath the surface

    Recognize

    Agentic analysis separates noise from signal and prioritizes the exposures, vulnerabilities, and configurations that need attention.

    prioritize → critical findings

  3. 03

    Dives with precision

    Act

    Every finding becomes a remediation playbook with clear steps to fix the issue and verify the outcome.

    remediate → outcome verified

// Beyond detection

Detection is only part of the work.

We turn findings into remediation playbooks: practical guides explaining what needs attention, why it matters, and which steps to follow to address it and verify the outcome. This helps teams move from technical alerts to informed decisions.

What needs attention
DMARC policy is set to p=none.
Why it matters
Anyone can spoof the domain in phishing campaigns.
Steps
  1. 1Publish SPF with the authorized senders.
  2. 2Sign outbound mail with DKIM.
  3. 3Raise DMARC to p=quarantine, then p=reject.

Illustrative demo

From Guatemala, we are building cybersecurity that is clearer, more practical, and more accessible to the organizations protecting what they are creating.
