The Public-Facing Infrastructure RingWarden Reviews.
A cybersecurity assessment for accounting firms is only as useful as the areas it covers. Here is a detailed look at the DNS, email authentication, portal, and transport-security checks behind the RingWarden Professional Security Assessment.
Your firm's website, client portals, email infrastructure, and other internet-facing systems make up its public-facing digital footprint. For accounting and tax businesses, that footprint is where confidential client information, taxpayer records, and financial documents intersect with the open internet.
RingWarden reviews that footprint using publicly available information, then investigates and validates potential findings. The areas below are the core of what a professional security assessment examines — and each one is reported in plain language with severity context and practical recommendations.
A potential weakness does not automatically mean a breach has occurred. It means the issue deserves appropriate investigation.
Six areas that shape your firm's security posture.
Each area is examined with publicly available information, then investigated and validated before being represented as a confirmed finding.
DNS configuration
Your domain's DNS records shape how the internet reaches your firm's services. Misconfigurations can expose systems you no longer use or intended to keep private.
What we look at
- Subdomains that resolve to live services, including legacy or forgotten hosts.
- DNS records that point to infrastructure no longer under your firm's control.
- Missing or misconfigured DNSSEC where it would be appropriate.
- Inconsistent or stale records across nameservers.
Why it matters: Forgotten subdomains and dangling DNS records are a common source of unintended exposure. Identifying them is a sensible first step in reducing your public-facing footprint.
Email authentication (SPF, DKIM, DMARC)
Email is how your clients receive invoices, document requests, and tax filings. Without proper authentication, your domain can be spoofed to impersonate your firm.
What we look at
- Whether an SPF record is published and which senders it authorizes.
- Whether DKIM signing is in place for outbound mail.
- Whether a DMARC policy is published, and whether it is set to enforce or monitor.
- Alignment between SPF, DKIM, and the visible From: domain.
Why it matters: Accounting and tax firms are frequent targets for impersonation. Email authentication helps your clients distinguish genuine correspondence from a spoofed message pretending to be your firm.
Client portals & login systems
Portals where clients upload documents or view financial information are among the most sensitive entry points on your public-facing footprint.
What we look at
- Transport security (TLS) on portal and authentication endpoints.
- Presence of security headers that protect authenticated sessions.
- Whether administrative interfaces are reachable from the public internet.
- Certificate validity and configuration on login pages.
Why it matters: A portal is where confidential client documents live. Reviewing its public-facing configuration is a proportionate part of understanding your exposure — without logging in or accessing private data.
Exposed services & infrastructure
Every system reachable from the internet is part of your attack surface. Knowing what is exposed is the foundation of any assessment.
What we look at
- Internet-facing services associated with your domain and known infrastructure.
- Administrative or management interfaces reachable without restriction.
- Services running software behind the current supported release.
- Endpoints accepting outdated or deprecated transport protocols.
Why it matters: You can't protect what you don't know is there. Mapping exposed services gives your firm a clearer picture of where attention is warranted.
TLS & transport security
Transport encryption protects data in transit between your clients and your systems. Weak or outdated configuration can undermine that protection.
What we look at
- Supported TLS versions and cipher suites on public endpoints.
- Certificate validity, chain, and hostname coverage.
- Presence and configuration of HSTS (HTTP Strict Transport Security).
- Redirect behavior from insecure to secure connections.
Why it matters: Deprecating older TLS versions and enforcing modern transport security is a practical, low-friction way to strengthen the connection your clients rely on.
Security headers & application posture
HTTP security headers instruct browsers on how to handle your site's content. Their absence can leave visitors and sessions less protected.
What we look at
- Content-Security-Policy and whether it constrains untrusted sources.
- X-Frame-Options or frame-ancestors controls against clickjacking.
- X-Content-Type-Options and referrer policy configuration.
- Permissions-Policy for browser features such as camera, microphone, and geolocation.
Why it matters: Security headers are a straightforward hardening layer. Reviewing them is a sensible part of understanding how your public-facing application is configured.
Public information. Authorized investigation. Clear reporting.
Public information first
RingWarden begins with publicly available information about your firm's digital footprint — no logins, no code injection, no access to private client data.
Investigate & validate
Potential findings are investigated and validated. We distinguish preliminary indicators from confirmed findings and only report what we can substantiate.
Clear, prioritized report
You receive a written report with severity context and practical recommendations — plain language, not jargon, prioritized by what matters.
Any deeper testing that requires authorization will only take place after you authorize it and the scope is agreed upon. The preliminary quickscan does not log into private systems or access private client records.
All of this is included in the Professional Security Assessment.
The areas above are reviewed, investigated, and validated, then delivered as a professional written report with severity context and practical recommendations.
- Review of relevant preliminary security findings.
- Further investigation and validation of potential issues.
- Clear explanations of confirmed findings.
- Severity and risk context where applicable.
- Practical recommendations for addressing identified issues.
- A professional written assessment report.
