An email risk assessment is a deep-dive checkup that finds the hidden weak spots in your company's email setup. It protects you against obvious junk mail and commodity malware sent to your inbox. But more importantly, it looks for gaps where modern, targeted scams and identity‑driven attacks can slip through. These advanced scams include:

• Phishing: Fake messages that impersonate trusted brands or services to trick you into entering your credentials or clicking a malicious link that can steal data or drop malware
• Vishing: Fraudulent phone calls or voicemails where scammers impersonate banks, government agencies, or even family members and pressure you into verbally revealing sensitive data or taking risky actions
• Smishing (SMS phishing): Deceptive text messages that exploit immediate urgency—like fake delivery failures or fraud alerts—to trick you into clicking malicious links or downloading malware
• Business email compromise (BEC): A threat actor hijacking or spoofing a business email account and impersonating a CEO, CFO, or vendor to trigger fraudulent wire transfers, payroll changes, or sensitive data sharing
• Session hijacking: Stealing a valid session token from an active login so the attacker can bypass the password and MFA checks and take over the user's email and cloud apps
• Account takeover: Using stolen or reused credentials to log into an employee's account, change settings and forwarding rules, and impersonate them to steal data or commit fraud from the inside

To make your business safer, you must first acknowledge the gaps in your current security tools. For example, standard email security gateways are great at blocking mass spam and virus attachments, but modern threat actors rarely use those old tactics. Instead, they rely on social engineering—building trust through believable impersonation. Once they trick an employee, they can steal invoices or payroll data without setting off a single security alarm because the employee willingly handed over the information. To stop them, you need tools that watch for unusual behavior and subtle red flags that basic security controls miss.

Benefits of email security risk assessment

Running regular audits protects your business in these ways:

• Proactive vulnerability management: Find and fix security weaknesses before threat actors ever get a chance to use them against you.
• Effective financial loss prevention: Prevent attacks like business email compromise (BEC) before they result in fraudulent wire transfers or payroll theft.
• Enhanced regulatory compliance: Stay aligned with major security and privacy frameworks and regulations such as HIPAA, PCI, SOC 2, GDPR, or CMMC.
• Uninterrupted business continuity: Keep operations running by preventing costly security incidents that can shut down daily work.

To build a strong defense, you need to review your email practices. A truly effective assessment focuses on the following areas.

Asset identification: People and technology

Before you can protect your business, you need to identify both your high-value personnel and your digital assets:

• The people: Scammers target individuals, not just computers, frequently impersonating high-level executives to intimidate lower-level employees into bypassing security protocols or surrendering credentials. Because a threat actor can escalate across the network using any valid login, an audit is critical to uncover what employee data is exposed publicly. This process identifies potential victims of credential harvesting or past data breaches before hackers can exploit them.
• The technology: This means keeping a clean inventory of every email account and server you own. It also means tracking down old, unused employee inboxes. Threat actors love to break into abandoned or unmonitored accounts for internal phishing, BEC, and data exfiltration, so the risk is not just an "unmonitored inbox" but continued access to data and systems.

Technical controls review: Authentication, authorization, and monitoring

A thorough technical controls review helps lower your exposure to email security threats. Consider the following:

• Email identity checks (SPF, DKIM, DMARC): These are digital authentication seals for your email, added directly to your domain's public domain name system (DNS) settings in the configuration dashboard. These seals prove to the rest of the world that an email claiming to be from your company actually came from you, preventing threat actors from faking your company domain name.
• Conditional access policies: Instead of just asking for a password, this security layer looks at the surrounding context. For example, your system can strictly enforce multi-factor authentication (MFA) across all user profiles. If an employee tries to log into their email using an unrecognized phone from an unfamiliar country, the system automatically blocks them.
• Mailbox forwarding rules: These settings control whether an email is automatically forwarded to external recipients, which is a common method threat actors use to silently copy data out of your environment.
• App permissions (OAuth): This checks what external apps employees have connected to their work email (like connecting a calendar app or phone game). If a scammer tricks an employee into approving a malicious app, that connection grants the threat actor a back door into your company's data without needing a password.

User risk profiling: Identifying who threat actors target most

Because every employee holds a different level of responsibility, you can't apply a blanket security policy to everyone.

While a junior assistant may face a high volume of everyday scams, a finance director who can approve million-dollar wire transfers is a higher-value target. To counter this, the assessment maps out which employees scammers target most, how much access they have, and how vulnerable they are to advanced phishing techniques. It then uses this data to build distinct risk profiles for different roles.

With these profiles programmed into your security system, the software automatically responds the moment it detects a risk factor. For example, a high-value finance profile might attempt an unusual action, like downloading a bulk vendor list or logging in outside of standard working hours. The system automatically demands two-factor authentication or freezes the session until the activity can be verified.

Threat analysis: Finding email security compliance gaps

Earning compliance certifications like SOC 2 or HIPAA proves your active defenses meet industry-standard baselines. However, checking off a compliance list isn't the same as optimizing for real-world attacks. To determine if your current setup qualifies as a true security email system, you have to look beyond static encryption and evaluate how aggressively your network hunts down and neutralizes active intruders.

It's crucial to continuously assess your email risks and adapt based on actual findings because cyber threats evolve in real time. Static defenses grow blind spots as attackers pivot their tactics to slip past traditional filters. And your company's risk surface changes daily as employees change roles and inherit new access privileges.

To stay ahead of these tactics, use a solution like Huntress Managed ITDR, which combines smart AI-centric detection logic with human experts who watch your Microsoft 365 accounts 24/7. While your team is asleep, these experts look for the subtle movements of a threat actor to stop account break-ins in real time.

To truly understand how safe your company's email is, you need to combine outside security tools with Microsoft's and Google's built-in features and pull your findings together in a report. Here are some practical tips to get started:

• Define scope and purpose: Figure out why you're running an assessment, for example to uncover sophisticated attacks or ensure regulatory compliance. Knowing your goal helps you narrow down which employee inboxes and devices you need to review.
• Check baseline controls: Confirm that everyone has enabled MFA and that your authentication seals (SPF, DKIM, and DMARC) verify your domain name correctly. Review any outside app permissions to ensure no third-party software has a hidden back door into an unmonitored inbox.
• Use Microsoft Defender tools: Generate actionable checklists to lock down user access and data protection using Microsoft Secure Score in the Microsoft Defender Portal. This tool grades your infrastructure and provides steps to fix security vulnerabilities like missing MFA or unencrypted data storage. You can also send simulated phishing attempts to help your team practice spotting real-world tricks.
• Detect, respond, and adapt: Investigate red flags, including impossible travel patterns, unauthorized forwarding rules, and suspicious inbox rules filtering specific keywords like "invoices" or "payroll." Drill down into these activities by auditing the user's recent sign-in logs and rule configurations to confirm a breach. Once verified, immediately lock down the threat by terminating all active login sessions, blocking account access, and deleting the malicious rules.
• Set rules and provide training: Create and communicate clear policies to guide employee actions and set expectations. Teach your team to practice consistent habits, like hovering over links to verify the destination URL for lookalike domain names, and reporting suspicious email activity immediately.

A thorough email risk assessment reveals hidden weak spots and highlights the gaps left behind by standard gateway security. But an audit only shows you a snapshot of a single day. To stay completely safe, you also need continuous monitoring to catch threat actors the moment they try to break in.

Together, regular risk assessments and ongoing monitoring help you spot and stop threat actors inside your Microsoft 365 accounts before they can damage your reputation or your revenue.

Managed ITDR continuously monitors, investigates, and responds to risks inside your Microsoft 365 and Google Workspace environments. The software instantly flags sneaky behavior, like impossible travel patterns or sign-ins from suspicious networks.

Then, a live 24/7 Security Operations Center (SOC) investigates these flags to verify whether the account activity belongs to a legitimate employee or an active intruder. Once they confirm a threat, they take action to freeze the risk—instantly logging the hacker out, disabling the compromised account, and deleting malicious forwarding rules before any damage is done.
