Email Security Rating
Managing the "Email Security" Rating: Protecting the Front Door of Your Organization
In the ecosystem of third-party risk management (TPRM), Email Security is widely considered the "Canary in the Coal Mine." Because email remains the primary vector for ransomware, phishing, and Business Email Compromise (BEC), rating agencies (such as BitSight, SecurityScorecard, and UpGuard) place significant weight on this category.
At ThreatNG, we understand that a low Email Security score does more than just lower your average; it signals to cyber insurers and partners that your organization is "spoofable." It suggests you lack control over who can send messages on your behalf. However, automated scanners often penalize legitimate infrastructure or fail to recognize complex, secure configurations. This guide explains how to use the ThreatNG ecosystem to take control of your Email Security narrative.
Understanding the Email Security Rating
To improve your score, you must understand the mechanics of the grade. Email Security ratings are an "outside-in" assessment of your domain's authentication protocols. They do not analyze your internal spam filters or employee training; they analyze your DNS records to determine if you are preventing impersonation.
The score is primarily derived from three pillars:
SPF (Sender Policy Framework): Is there a record listing authorized IPs? Is it set to "Hard Fail" (-all) or the more permissive "Soft Fail" (~all)?
DKIM (DomainKeys Identified Mail): Are messages cryptographically signed to prove integrity?
DMARC (Domain-based Message Authentication, Reporting, and Conformance): Do you have a policy that tells receivers to quarantine or reject unauthenticated mail? (This is the "Gold Standard" for ratings).
The Challenge: Automated scanners are context-blind. They flag a "Soft Fail" SPF record as a critical vulnerability, even if it's a temporary transition state. They penalize "Shadow" marketing domains you didn't know existed. Without context, a strategic migration can appear negligent.
The ThreatNG Strategy: Opportunity, Refutation, and Defense
Managing your Email Security rating isn't just about editing TXT records; it's about governing your digital identity. ThreatNG empowers you to move from a reactive "cleanup" mode to a proactive governance strategy.
1. Proactive Opportunity Finding (Beating the Algorithm)
The most effective way to manage an Email Security rating is to identify unauthorized senders and configuration gaps before an external auditor flags them. Rating agencies scan periodically; ThreatNG scans continuously. By combining Investigation Modules, Intelligence Repositories, Dynamic Entity Management, and our predictive ThreatNG Security Ratings, you can identify threats before they impact a rating.
The Strategy: You begin by populating Dynamic Entity Management with specific People (e.g., Marketing VPs), Places (e.g., Regional Sales Offices), and Brands (e.g., "Project Launch X"). As soon as these entities are defined, ThreatNG continuously hunts for exposures related to them.
The Example: Imagine your Marketing VP (tracked as a "Person" entity) authorizes a new newsletter service for "Project Launch X" (tracked as a "Brand" entity). The team sets up a subdomain (news.projectx.com) but fails to configure DMARC.
Detection: Domain Intelligence immediately detects the new subdomain associated with the brand entity.
The Exposure: Simultaneously, Sensitive Code Exposure detected that the project's developer accidentally posted the SendGrid API keys for this domain in a public repository.
Internal Rating Check: ThreatNG's internal BEC & Phishing Susceptibility rating for this asset drops to a 'D', and the Non-Human Identity Exposure score worsens due to the leaked keys.
The Governance: Because your Customizable and Granular Risk Configuration is tuned to Averse, ThreatNG immediately flags "API Key Leak" and "Missing DMARC on New Brand Asset" as Critical Violations. You revoke the keys and enforce DMARC during the "Grace Period" before the rating agency ever sees the domain.
A World of Possibilities: Crucially, this is just one example of the many possibilities with ThreatNG. You could also use Dark Web Presence to identify compromised credentials for an administrator account that has access to your DNS registrar (allowing attackers to alter your SPF records and tank your Cyber Risk Exposure rating), use Online Sharing Exposure to detect leaked corporate mailing lists on paste sites (signaling a breach of data privacy protocols), or use Social Media monitoring to detect a rise in customer complaints about "spam" coming from your domain, signaling a spoofing campaign is underway before technical scanners catch it.
2. Challenging Inaccuracies (The Refutation Strategy)
A significant portion of Email Security penalties stems from Asset Misattribution. You may be penalized for a domain that sends no email, or for a domain you sold years ago. To dispute this, you need forensic evidence gathered by Investigation Modules and backed by Policy Management.
The Strategy: When a rating agency penalizes you for a theoretical risk in a non-email domain, you need to prove it is effectively "parked" for email purposes.
The Example: A rating agency penalizes your score for "Missing DMARC" on a defensive registration (e.g., yourbrand-typo.com).
The Evidence: You use Domain Intelligence to prove the domain has no MX (Mail Exchange) records. You verify via Archive Web Pages and Search Engine Exploitation that the domain has never been active or indexed.
The Classification: You then use Dynamic Entity Management to auto-classify this asset as "Parked / Defensive."
The Report: You generate a report using Granular Risk Scoring that shows that, while the agency rates this as a "High" risk, your internal policy rates it as "Low Risk" (Acceptable). Furthermore, you note your ThreatNG Brand Damage Susceptibility rating, which remains an 'A' because the domain is effectively inert, providing irrefutable datato refute the finding.
A World of Possibilities: It is important to emphasize that this is only one of many possibilities. You might also use SEC 8-K Filings intelligence to prove a domain belongs to a divested entity that is no longer your legal responsibility (improving your Supply Chain & Third Party Risk Exposure score), use Sentiment and Financials to show the market recognizes a different owner, or use Technology Stack analysis to prove that an IP flagged as an "Open Relay" is actually a Honeypot designed to trap spammers, not facilitate them.
3. Demonstrating Context & Control (The Bolstering Strategy)
Often, an Email Security finding is technically accurate (e.g., "SPF Record uses Soft Fail"), but the configuration is a deliberate business requirement during a migration. A scanner sees a vulnerability; you see a transition plan. Here, your goal shifts from refuting the data to bolstering the context using technical validation and Exception Management.
The Strategy: You use ThreatNG to prove that compensating controls exist, and then use Policy Management to prove that the risk is governed, not ignored.
The Example: A rating agency flags your main domain for using ~all (Soft Fail) in SPF, claiming it allows spoofing.
The Evidence: You use DarChain Attack Path Intelligence to demonstrate that you are in a "Monitoring Phase" of a DMARC rollout, and that your DMARC record is set to p=quarantine, which effectively overrides the SPF Soft Fail for enforcement purposes.
The Validation: You reference your ThreatNG Breach & Ransomware Susceptibility rating, which remains low because the DMARC policy blocks the actual attack vector.
The Governance: To satisfy auditors, you use Exception Management to formally document this configuration as a "Managed Exception" with a defined migration timeline. This creates an audit trail proving to stakeholders that the configuration is a governed "Authorized Operation," not an error.
A World of Possibilities: Explicitly, this is just one example of the many possibilities available with ThreatNG. You could also use Social Media intelligence to prove you are publicly communicating a trusted sender list to customers (mitigating confusion and protecting your ESG Exposure score related to customer trust), use Mobile App Exposure to show that email is handled via API rather than SMTP for your mobile users (reducing the attack surface), or use Ransomware Gang Activity intelligence to show that while your SPF is temporarily permissive, your domain is not currently a target of active campaigns, justifying your prioritized remediation schedule.
The ThreatNG Ecosystem Advantage
ThreatNG provides the contextual intelligence required to turn a static checklist into a dynamic security strategy. Here is how our specific pillars support a superior Email Security rating:
Validating the Perimeter: External Discovery ensures you find "Shadow Mail" infrastructure (like rogue marketing automation accounts) before rating agencies do, while our internal ThreatNG Security Ratings (like BEC & Phishing Susceptibility and Data Leak Susceptibility) provide a "pre-flight" check, giving you a benchmark to measure your progress before the official audit.
Threat-Led Context: We move beyond simple checklists by integrating deep Intelligence Repositories. We correlate your assets against Compromised Credentials, Bug Bounties, Bank Identification Numbers, and Vulnerability Intelligence (EPSS, KEV). This allows you to prioritize Email Security fixes based on the current threat landscape (e.g., "Are phishing kits targeting my industry?") rather than relying solely on static best practices.
Proving Logic with DarChain: Finally, DarChain Attack Path Intelligence uses the "Finding -> Path -> Step -> Tool" logic to cut through the noise. It helps you prioritize the 5% of Email Security issues that actually lead to a breach (like a true BEC opportunity), ensuring you govern true risk rather than just chase a score.
