Phishing simulations are an effective way to test how employees respond to suspicious emails in a controlled environment. They can reveal whether users recognize warning signs, click questionable links, submit information, or report suspicious messages to the security team.
But running a phishing simulation is only the beginning. Organizations also need to understand why users responded in a particular way and what those results indicate about their overall email security posture.
A detailed review should combine simulation statistics with technical email analysis and employee response patterns.
Why Phishing Simulation Results Need Proper Analysis
It can be tempting to judge an entire phishing campaign using a single metric, such as the percentage of employees who clicked a link.
Suppose only 8% of employees clicked the simulated phishing link. At first glance, the result may appear positive. But what if most of those employees also entered their credentials? What if nobody reported the suspicious email for the next hour?
These additional findings can completely change the interpretation of the simulation.
Therefore, organizations should examine the complete sequence of events rather than treating click rate as the only measure of success.
Which Phishing Simulation Metrics Matter?
Begin the investigation by collecting the major campaign statistics.
Important metrics include:
- Email delivery rate
- Link click rate
- Credential submission rate
- Attachment interaction rate
- Employee reporting rate
- Average time to click
- Average time to report
These metrics provide a general picture of how employees responded.
The credential submission rate deserves particular attention. Clicking a suspicious link creates potential exposure, but entering login credentials into a fraudulent page could provide an attacker with direct access to an account during a real attack.
Reporting behavior is equally important. Employees who quickly report suspicious messages can give security teams valuable time to respond before the threat spreads further.
Analyze What Made the Email Convincing
The next question is simple: Why did employees trust the message?
Phishing campaigns frequently rely on social engineering rather than sophisticated technical techniques.
Attackers may create urgency by claiming that an account will be suspended, a password is about to expire, or immediate verification is required.
Other campaigns imitate everyday workplace communications such as:
- Microsoft 365 notifications
- Shared documents
- Payment requests
- HR announcements
- Invoice notifications
- Password reset messages
- Package delivery updates
Determine which elements generated the most interactions during the simulation.
Organizations that want to understand the complete investigation process can explore How to Analyze a Phishing Email Simulation for a structured approach covering metrics, technical evidence, user behavior, and remediation.
Inspect the Email Header
Technical examination should begin with the complete email header.
An email header can reveal information that users normally cannot see in their inbox interface. This may include the servers involved in delivering the message, timestamps, sender information, authentication results, and routing details.
Analysts should examine important fields such as:
- From
- Return-Path
- Received
- Message-ID
- Reply-To
- Authentication-Results
SPF, DKIM, and DMARC results should also be reviewed.
These email authentication mechanisms can help determine whether a message originated from authorized infrastructure and whether existing security configurations responded correctly.
During a simulation, reviewing these results can help security teams identify weaknesses that could potentially affect their ability to detect real spoofed or malicious emails.
Examine URLs and Landing Pages
Phishing links deserve detailed investigation because the text displayed to a recipient may be completely different from the actual destination.
Check the complete URL and identify:
- Destination domain
- Redirects
- URL shortening services
- Lookalike domain names
- Unusual subdomains
- HTTP or HTTPS usage
The landing page should also be evaluated.
Ask whether it closely resembles a trusted website, whether it requests login information, and which visual or textual elements may have convinced employees that the page was legitimate.
These observations can provide valuable material for future awareness training.
Compare Click Time With Reporting Time
Speed is an important but frequently overlooked element of phishing simulation analysis.
Imagine an employee clicking the simulated phishing link two minutes after receiving the message. The first phishing report, however, reaches the security team 25 minutes later.
During an actual attack, those 23 minutes could provide an attacker with enough time to collect credentials or target additional employees.
Security teams should therefore compare two important measurements:
Time to Click vs. Time to Report
A strong security culture should gradually reduce the time employees require to identify and report suspicious messages.
Look for Patterns Across Employees and Departments
Avoid evaluating every employee using the same risk profile.
Different departments encounter different types of emails during their normal work.
Finance teams frequently receive invoices and payment requests. HR departments receive resumes and external documents. Executives may receive urgent requests from numerous internal and external contacts.
Attackers understand these patterns and often customize phishing campaigns accordingly.
Break simulation results down by department, role, or business function. This can reveal whether particular groups consistently demonstrate higher click rates or slower reporting times.
Such information can then be used to create more relevant training exercises.
When Email Forensics Becomes Important
Manual analysis may be sufficient when examining a handful of messages. However, reviewing large numbers of emails can quickly become difficult when analysts need to compare headers, URLs, metadata, timestamps, attachments, and communication relationships.
Using professional Email Forensics Software can help investigators examine large collections of email evidence more efficiently.
Forensic capabilities can assist with activities such as searching email headers, investigating links, analyzing communication patterns, reviewing message properties, and creating timelines of email activity.
This becomes especially useful when an organization wants to compare simulation data against actual suspicious emails received by employees.
Instead of treating each email as an isolated incident, investigators can identify relationships between senders, domains, URLs, keywords, and communication events.
Turn Findings Into Practical Improvements
The final stage of phishing simulation analysis should always focus on improvement.
Employees who interacted with the simulation should receive specific guidance about what they missed.
For example, if employees trusted a message because of its display name, training should demonstrate how to inspect the complete sender address.
If an urgent warning caused users to click immediately, explain how attackers use urgency to prevent recipients from carefully evaluating a message.
Future phishing simulations should then test the same weaknesses using different scenarios.
This creates a continuous cycle:
Simulate → Analyze → Identify Weaknesses → Train → Test Again
Over time, organizations can determine whether click rates are decreasing, reporting rates are increasing, and employees are responding to suspicious emails more quickly.
Final Thoughts
A phishing email simulation should provide more than a percentage showing how many employees clicked a link.
Organizations should investigate the complete story behind the campaign by examining click and credential submission rates, reporting behavior, response times, email headers, authentication results, URLs, and departmental patterns.
When these findings are combined with email forensic analysis and targeted employee training, phishing simulations become much more valuable.
Instead of simply testing whether employees fail or pass an exercise, organizations can use each simulation to discover security gaps, strengthen awareness, and improve their ability to respond to real phishing threats.
