It's 9:17 on a Wednesday morning.
An employee receives an email that appears to come from Microsoft 365.
"Your account requires immediate verification to prevent service interruption."
The message includes the company logo, a familiar-looking sign-in button, and a warning that access could be suspended.
The employee has several meetings scheduled and doesn't want to lose access to email.
So they click.
A login page appears. Something feels slightly unusual, but they're already halfway through their morning routine.
A few seconds later, they realize the website might not be legitimate.
What happens next could make a significant difference in how the business handles a potential security incident.
For small and medium-sized businesses, phishing attacks are not simply an email problem. They can expose employee accounts, sensitive business information, and connected systems.
The good news is that clicking a suspicious link doesn't automatically mean the entire business has been compromised.
But it does mean the situation deserves attention.
Here's what employees, managers, and IT teams should do.
Phishing is a form of social engineering in which attackers impersonate trusted people, companies, or services to convince someone to reveal information or perform an unsafe action.
For example, an attacker might send an email that appears to come from:
The consequences depend on what happened after the employee clicked.
The employee may have opened a malicious or fraudulent webpage without providing credentials or downloading anything.
That is generally less concerning than submitting a password, but it doesn't eliminate every risk.
The employee should stop interacting with the page and notify IT so the link and device activity can be assessed.
This creates a more serious concern.
An attacker might use stolen credentials to attempt account access, particularly if the same password is reused across multiple systems.
Some modern phishing techniques also attempt to capture authentication sessions or manipulate multifactor authentication processes.
The affected account requires prompt investigation and appropriate protective actions.
A malicious attachment or download could expose a workstation to malware or unauthorized software.
The response may require device isolation, security investigation, and a controlled recovery process.
The key distinction is that different phishing incidents require different responses.
That's why employees should report exactly what happened rather than assuming the outcome.
When an employee suspects they clicked a phishing link, the priority is to prevent further interaction and alert the appropriate people.
Do not enter additional information, approve unexpected authentication requests, or download anything from the page.
Avoid revisiting the website to investigate it yourself.
If a file was downloaded, do not open or run it.
Report the incident through an established, trusted company communication channel.
Provide the details you remember:
Do not forward the suspicious link to coworkers for them to investigate.
Your security team may ask you to preserve the original email so they can examine it safely.
If a suspicious download was executed or malware is suspected, IT may recommend disconnecting the device from the network to limit potential spread.
Employees should follow the organization's incident response procedure rather than independently wiping, resetting, or restarting devices.
An uncontrolled reset could remove information needed to understand what happened.
If you entered a password, tell IT immediately.
Use a trusted, unaffected device to change the compromised password, especially if the password is used elsewhere.
Your administrator may need to revoke active sessions, review multifactor authentication settings, or temporarily restrict account access.
If financial information was submitted, contact the relevant financial institution using a verified phone number or website.
These actions can help reduce further exposure while the incident is investigated.
Employee reporting is only the beginning.
The IT or cybersecurity team should determine whether the suspicious activity resulted in unauthorized access, malware execution, or exposure of sensitive information.
The investigation may include several areas.
Examine unusual login attempts, unfamiliar locations, unexpected devices, and authentication activity associated with the affected account.
A suspicious sign-in does not automatically prove compromise, but it may require further investigation.
If a Microsoft 365 account may have been compromised, administrators should consider reviewing:
Password resets alone may not address every form of account compromise.
Microsoft provides specific recommendations for securing compromised Microsoft 365 accounts, including session revocation and reviewing unauthorized authentication methods.
Endpoint security tools and relevant system logs can help identify suspicious downloads, processes, or changes.
If malicious activity is confirmed, the device should be handled according to the organization's incident response procedures.
A single reported email may be part of a broader campaign.
IT teams may need to search for related messages, review alerts, and block confirmed malicious senders, URLs, or indicators using available security controls.
The goal is to protect other employees before they encounter the same threat.
Depending on the incident, the organization may need to determine whether business records, customer data, or financial information were accessed.
Any applicable contractual, regulatory, or legal notification requirements should be evaluated with the responsible internal teams and qualified advisers.
One of the biggest challenges with phishing incident response isn't always technology.
It's human behavior.
Imagine an employee realizing they clicked a suspicious link.
They're embarrassed.
They worry their manager will be upset or that they'll be blamed for putting the business at risk.
So they close the browser and say nothing.
Hours later, the security team discovers unusual account activity.
Now the organization must investigate without knowing exactly when the original interaction occurred.
This is why cybersecurity awareness should go beyond teaching employees to recognize suspicious messages.
Employees also need to feel comfortable reporting potential mistakes immediately.
A healthy reporting culture encourages people to speak up before a small concern becomes a more complicated incident.
Training should communicate a simple message:
If something seems suspicious, report it. Even if you're unsure whether anything happened.
Phishing protection works best when it combines technology, employee awareness, and established response procedures.
Email security tools can help detect suspicious messages, malicious links, and impersonation attempts.
They reduce exposure but cannot guarantee that every dangerous message will be blocked.
Multifactor authentication provides an important additional layer of account protection.
Organizations should consider phishing-resistant authentication methods where practical, especially for privileged and high-risk accounts.
Managed endpoint protection, software updates, and security monitoring can help detect and respond to suspicious device activity.
Every employee should know how to report suspicious emails and who to contact if they believe they've interacted with a malicious link.
Organizations should periodically review how they would handle compromised credentials, malicious downloads, and business email compromise.

Potentially. A phishing link may lead to a fraudulent login page, malicious download, or exploit attempt. Simply opening a page doesn't necessarily mean the device is infected, but suspicious activity should be reported and assessed.
The employee should stop interacting with the page, report the incident, and follow IT instructions. The risk may be lower if no information was submitted and nothing was downloaded, but a security review is still appropriate.
If credentials were entered, the affected account should be secured promptly from a trusted device, with IT involvement. A password change alone may not be sufficient if an attacker obtained an active authentication session or other access.
No. MFA significantly strengthens account security, but certain phishing techniques can target authentication sessions or trick people into approving fraudulent requests. Phishing-resistant MFA can provide stronger protection against these methods.
The organization should activate its incident response process, secure the affected account, investigate sign-in and mailbox activity, assess potential data exposure, and determine whether additional systems or users were affected.
Employees are human.
Even experienced professionals can encounter convincing phishing attempts during a busy workday.
What matters is whether the organization has the right procedures, protections, and support to respond.
A suspicious click doesn't always lead to an incident.
But when something does go wrong, preparation and coordinated action can make a meaningful difference.
Cybersecurity isn't about expecting employees to be perfect. It's about building a business that's prepared when people make mistakes.
