AI-Generated Summary
What this means
revlo.co scored 57/100 and does not meet the minimum security posture threshold. The most critical issue is: Set up email authentication (DMARC, SPF, DKIM). This must be addressed before the vendor can be approved for procurement or data processing activities.
Critical gaps in: DMARC / Email Security. Positive signals: Known Breaches, TLS Configuration, CVE Exposure all passed.
3 action items identified, including 1 critical. The issues are configuration gaps, not architectural problems. A focused remediation effort of 2–5 days could address all findings.

Security checks
Each check inspects a different part of revlo.co's public security setup. Green means healthy, yellow needs attention, red is a problem.
DMARC / Email Security
Issues: No DMARC record found — email spoofing is not prevented; No SPF record found; No DKIM records found for common selectors (domain may use custom selectors — this is not a confirmed gap).
DNS Configuration
Strengths: 2 nameservers configured (chad.ns.cloudflare.com., princess.ns.cloudflare.com.); Zone transfers properly restricted. Issues: DNSSEC not configured — DNS responses can be spoofed.
Certificate Hygiene
Strengths: Certificate valid, 63 days remaining; Issued by Google Trust Services. Issues: Wildcard certificate in use — broader attack surface if compromised.
HSTS Header
Could not fetch https://revlo.co — connection failed or timed out.
Security Headers
Could not fetch https://revlo.co — connection failed or timed out.
Known Breaches
No known breaches found in public disclosure databases.
TLS Configuration
TLSv1.3 negotiated with TLS_AES_256_GCM_SHA384 (256-bit). Strong configuration with no deprecated protocols or weak ciphers detected.
CVE Exposure
No server software versions detected in HTTP response headers. This is good practice (version hiding) but means CVE exposure cannot be assessed from external signals alone.
Recommended actions
3 items
Steps to improve revlo.co's security grade, ranked by impact.
1
Set up email authentication (DMARC, SPF, DKIM)
Without email authentication, anyone can send emails that appear to come from revlo.co. This is the most common vector for phishing attacks targeting employees and customers. DMARC, SPF, DKIM are not configured.
Compliance impact
NIST CSFPR.AC-7
Email authentication is a required access control
ISO 27001A.13.2.1
Information transfer policies require email security controls
HIPAA§164.312(e)
Transmission security for electronic PHI
How to fix this
1
Add SPF record to DNS: v=spf1 include:_spf.google.com ~all (adjust for your email provider)
2
Configure DKIM signing with your email provider and publish the public key in DNS
3
Add DMARC record: v=DMARC1; p=quarantine; rua=mailto:[email protected]
4
Monitor DMARC reports for 2–4 weeks, then upgrade policy to p=reject

2
Enable DNSSEC on your domain
Without DNSSEC, DNS responses for revlo.co can be spoofed, potentially redirecting users to malicious sites. This requires coordination with your domain registrar to publish DS records.
Compliance impact
NIST 800-53SC-20
Secure name/address resolution service
How to fix this
1
Check if your DNS provider supports DNSSEC (Cloudflare, Route53, etc.)
2
Enable DNSSEC signing in your DNS provider dashboard
3
Add the DS record to your registrar for .co TLD
4
Verify: dig +dnssec revlo.co
3
Review certificate configuration
Certificate issues found for revlo.co: wildcard certificate in use. Wildcard certificates have a broader blast radius if compromised. These are operational hygiene items, not immediate security risks.
How to fix this
1
Consider replacing wildcard cert with individual certs for critical subdomains
2
Consolidate certificate issuance to 1–2 trusted CAs
