Featured Tools
Where Most Teams Start
A curated set of tools with the broadest applicability across IT operations, security, and compliance readiness.
Email, DNS & Web Security
SPF / DKIM / DMARC Checker
Verify email authentication records — SPF, DKIM, and DMARC — against any domain. Identify configuration gaps that expose your domain to spoofing.
Email, DNS & Web Security
DNS Health Checker
Full DNS diagnostic covering SPF, DKIM, DMARC, MX routing, and NS records. Identify operational misconfigurations before they cause incidents.
Email, DNS & Web Security
SSL Certificate Checker
Inspect SSL certificate validity, expiration, issuer, TLS version, and covered domains. Surface certificate issues before they disrupt services.
Security & Identity
Password Strength Checker
Evaluate an existing password against entropy, pattern-resistance, and modern NIST-aligned strength criteria, entirely in your browser.
Microsoft 365 & Entra ID
Microsoft 365 Security Readiness Assessment
Evaluate identity, email, device, and data protection baseline across four areas.
Compliance & Risk
Compliance Framework Selector
Identify which compliance frameworks actually apply to your organization based on industry, data types, and customer requirements.
Why We Built These
Operational Visibility Is Not Optional
Most organizations discover configuration gaps during audits, incidents, or migrations — not before. These tools exist to give IT teams proactive visibility into the areas that matter most.
Email Authentication
SPF, DKIM, and DMARC misconfigurations are among the most cited findings in compliance assessments — and one of the most straightforward to remediate.
DNS Governance
DNS errors are silent. Incorrect MX records drop inbound mail. Stale NS records cause intermittent failures. Neither surfaces obviously until customers complain.
Certificate Lifecycle
Expired certificates take HTTPS down immediately. Certificate monitoring is basic operational hygiene — yet a frequent source of preventable service disruptions.
Microsoft 365 Posture
M365 default configurations are not secure configurations. Identity, retention, backup, and external sharing all require intentional governance — not just activation.
Operational Guidance
Infrastructure Fundamentals
The operational domains these tools cover — email authentication, DNS, TLS, and Microsoft 365 — are foundational to infrastructure reliability and compliance readiness.
Operational domain
What governs it
Start here
SPF authorizes sending sources · DKIM validates message integrity · DMARC enforces authentication policy · Required for HIPAA and SOC 2 alignment
SPF / DKIM / DMARC Checker
MX routing redundancy prevents delivery failures · NS redundancy ensures resolution availability · TTL configuration affects propagation speed · DNS baseline documents pre-migration state
DNS Health Checker
Certificates require renewal before expiry · TLS 1.0 and 1.1 are deprecated · Self-signed certs break client trust · SAN coverage must match all service domains
SSL Certificate Checker
MFA is the highest-impact single control · Conditional Access enables context-aware enforcement · Legacy auth bypasses MFA entirely · Admin accounts require dedicated privileged identities
Identity & MFA Readiness Assessment
Microsoft retention ≠ backup · Third-party backup is a shared responsibility gap · External sharing defaults are often permissive · Audit logging must be verified as enabled
Microsoft 365 Security Checklist
Recovery objectives must be defined, not assumed · Backup coverage must be tested, not assumed · Business continuity plans require annual review · Vendor dependencies should be documented

FAQ
Questions About These Tools
Are these tools free to use?
Yes. All available tools are completely free to use with no account required. Some tools offer optional report delivery to your email after results are shown — this is never required to view results.
Do these tools access my systems or require credentials?
No. The DNS, email authentication, and SSL tools work entirely from publicly available DNS and certificate data — no system access, no credentials, no sign-in. The Microsoft 365 checklist is a local, interactive questionnaire that never connects to your tenant.
Who are these tools designed for?
IT administrators, operations managers, compliance officers, and governance teams at organizations that use Microsoft 365 or manage their own infrastructure. The tools are designed to be readable by non-technical stakeholders while providing actionable detail for technical teams.
How accurate are the DNS and SSL results?
DNS results are queried live via Cloudflare's DNS-over-HTTPS resolver and reflect current public DNS records. SSL results reflect the certificate presented on port 443 at the time of the check. Results are accurate for operational visibility purposes — they are not a substitute for a comprehensive security audit.
Will more tools be added?
Yes. The platform is actively expanding. Upcoming additions include Microsoft 365 external sharing analysis and additional infrastructure diagnostic utilities. Tools are built around the operational areas IT KORR supports.
