As of August 26, 2026 at 06:18, heizo.com has a security score of 89.7/100 (grade B: “Good”). CyStack’s automated assessment recorded 8 issues to review after completing 97.3% of applicable checks. The website owner should address “Email spoofing protection (DMARC)” first, then review the remaining items in order of impact.
At assessment time, CyStack did not find heizo.com or related infrastructure on any scam, phishing, or malware warning list after checking 5 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.
Check whether the website uses a secure connection and whether its HTTPS certificate remains valid.
Frequently asked questions
A valid SSL certificate still does not prove that heizo.com is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
HTTPS on heizo.com presented a certificate that was invalid or failed verification. The operator should review its validity dates, domain names, and trust chain.

CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
CyStack VulnScan continuously discovers assets, validates vulnerabilities, and helps security teams prioritize remediation across the enterprise.
These 3 failed checks or warnings have the greatest impact on the result for heizo.com.
Why it matters
DMARC lets the domain owner tell receiving services what to do when the visible From address is not verified by SPF or DKIM. Without DMARC, attackers have more opportunity to impersonate the domain in phishing email.
What to do
Publish a DMARC record at _dmarc, begin by collecting reports, and confirm that legitimate senders pass before applying a blocking policy.
