One of the most common questions security leaders ask when implementing a phishing simulation program is simple: How often should we run phishing simulations?
The answer depends on your organization’s risk profile, industry, workforce size, and security maturity. However, one thing is clear: running a phishing simulation once a year is no longer sufficient in today’s threat landscape.
Cybercriminals continuously evolve their tactics, and employees face phishing attempts every day. To build lasting security awareness and reduce human risk, phishing simulations must be conducted regularly and strategically.
This guide explains how often organizations should run phishing simulations and how to create an effective testing schedule.
Why Phishing Simulations Need to Be Ongoing
Many organizations treat phishing simulations as a compliance exercise.
A campaign is launched once a year, results are reviewed, and the program is considered complete.
Unfortunately, cyber threats do not operate on an annual schedule.
Employees change roles, new hires join the organization, business processes evolve, and attackers constantly develop new phishing techniques.
Just as organizations regularly test backups, disaster recovery plans, and security controls, they should continuously evaluate employee readiness against phishing attacks.
Regular phishing simulations help organizations:
- Measure employee awareness.
- Identify high-risk users.
- Reinforce secure behaviors.
- Track improvement over time.
- Reduce susceptibility to real-world attacks.
What Is the Recommended Frequency?
For most organizations, monthly phishing simulations provide the best balance between effectiveness and employee engagement.
Monthly testing allows security teams to:
- Measure trends consistently.
- Expose employees to different attack scenarios.
- Reinforce awareness throughout the year.
- Detect emerging risk patterns.
Employees gradually develop stronger threat recognition skills when phishing awareness becomes part of their regular work environment.
Recommended Phishing Simulation Schedule by Security Maturity
Organizations New to Phishing Simulations
If your organization is just starting, begin with quarterly phishing simulations.
This allows employees to become familiar with the process while giving security teams time to analyze results and improve awareness efforts.
Recommended frequency:
- Every 3 months.
Developing Security Programs
Organizations with established awareness programs should increase testing frequency.
Recommended frequency:
- Monthly simulations.
This approach provides better visibility into behavioral trends and helps maintain awareness throughout the year.
Mature Security Programs
Organizations with advanced security awareness initiatives often conduct simulations continuously.
Recommended frequency:
- Monthly campaigns.
- Additional targeted campaigns for high-risk groups.
- Scenario-based exercises throughout the year.
The objective shifts from awareness testing to ongoing human risk measurement.
Should Every Employee Receive the Same Simulation?
No.
One of the biggest mistakes organizations make is sending identical phishing emails to everyone.
Different users face different risks.
Finance Teams
Common attack types:
- Invoice fraud.
- Business Email Compromise.
- Payment diversion scams.
Human Resources
Common attack types:
- Fake job applications.
- Resume malware.
- Employee data requests.
Executives
Common attack types:
- Executive impersonation.
- Voice cloning attacks.
- Confidential data requests.
Tailoring simulations to employee roles produces more realistic and valuable results.
What About New Employees?
New employees should receive phishing awareness training and phishing simulations shortly after joining the organization.
The first few months of employment often represent a higher-risk period because employees are still learning internal processes and communication patterns.
Many organizations include phishing awareness as part of employee onboarding.
Signs You Are Running Simulations Too Infrequently
Your phishing simulation schedule may be insufficient if:
- Testing occurs only once or twice per year.
- Reporting rates remain stagnant.
- Employees consistently fail common phishing scenarios.
- New attack techniques are not included in simulations.
- Security teams lack visibility into human risk trends.
Infrequent testing makes it difficult to understand whether awareness efforts are improving security behavior.
Can You Run Too Many Phishing Simulations?
Yes.
Excessive testing can lead to employee fatigue and reduced engagement.
Problems can occur when:
- Employees receive phishing tests too frequently.
- Simulations become predictable.
- The same templates are reused repeatedly.
- Employees feel they are being monitored rather than educated.
The goal is not to trick employees continuously.
The goal is to help them recognize and respond to real-world threats.
For most organizations, monthly testing strikes the right balance.
How Phishing Simulations Support Compliance
Many compliance frameworks require organizations to establish security awareness programs.
Examples include:
- ISO 27001.
- SOC 2.
- PCI DSS.
- NIST Cybersecurity Framework.
- Various industry-specific regulations.
While these frameworks may not prescribe a specific phishing simulation frequency, regular testing helps demonstrate that awareness activities are active, measurable, and continuously improving.
A Practical Annual Phishing Simulation Plan
- January: Credential Harvesting Attack
- February: Business Email Compromise Scenario
- March: Cloud Service Login Phishing
- April: QR Code Phishing Simulation
- May: File Sharing Scam
- June: Executive Impersonation Attack
- July: IT Support Impersonation
- August: MFA Fatigue Scenario
- September: Vendor Invoice Fraud
- October: Cybersecurity Awareness Month Campaign
- November: Social Media-Based Phishing
- December: Holiday-Themed Phishing Attack
This approach exposes employees to a wide range of attack techniques throughout the year.
Key Takeaways
- Annual phishing simulations are generally insufficient for modern threat environments.
- Monthly phishing simulations are recommended for most organizations.
- Testing should reflect real-world attack scenarios relevant to employee roles.
- New employees should be included in phishing awareness efforts early.
- The goal is continuous risk reduction, not employee punishment.
- Phishing simulations should be part of a broader Human Risk Management strategy.
Conclusion
There is no single phishing simulation schedule that works for every organization. However, organizations that conduct phishing simulations regularly gain better visibility into employee behavior, emerging risks, and security awareness effectiveness.
For most organizations, monthly phishing simulations combined with ongoing awareness training provide the best balance between education, engagement, and measurable risk reduction.
As phishing attacks continue to evolve, organizations should view phishing simulations not as isolated awareness events but as an ongoing process for strengthening security culture and reducing human cyber risk over time.
