How to Protect Your Business From Phishing

Last updated on August 12, 2025

Phishing is one of the most serious forms of cyberattacks. Cybercriminals exploit human error and often use spoofed login pages or emails to steal passwords and other credentials. These attacks are particularly dangerous in today’s threat landscape, leading to data breaches, major financial and reputational losses, and service disruptions.

Why Is Phishing So Dangerous?

Ease of Execution – Social engineering attacks do not require sophisticated tools, only a carefully designed strategy.
Targeted and Personalized Attacks – spear-phishing and whaling specifically target certain departments or high-level decision-makers, increasing the likelihood of successful data theft.
Significant Financial Losses – The cost of data breaches and service downtime can reach millions of dollars.
Human Factor – Even well-trained employees sometimes make mistakes.

Market Statistics and Facts

The costs associated with data leaks due to phishing can reach several million dollars, not to mention reputational damage and legal consequences.
Phishing was responsible for 15% of all incidents in 2024.
As many as 68% of all security incidents are caused by employee errors.
Industry reports indicate that phishing often precedes other major attacks, such as ransomware, which in recent years has severely affected companies and public institutions.

The following chart shows the percentage of breach elements according to the Verizon Data Breach Investigations Report 2024. The percentages in the chart exceed 100% because a single incident can encompass multiple different breaches.

Safe Internet Use – Basic Protection Against Phishing

Do Not Open Suspicious Links or Attachments:
Always verify whether a message truly comes from a trusted source. If a link appears suspicious, type the website address into your browser manually instead of clicking the hyperlink.
Maintain Healthy Skepticism:
Phishing attacks often rely on urgency and emotional triggers. If you receive a message that worries you or demands immediate action, verify its authenticity by contacting the apparent sender directly.
Beware of Typos in Web Addresses:
Small spelling differences (e.g., “googlé.com” instead of “google.com”) can indicate a fake domain.
Protect Your Passwords:
Avoid using the same login and password combination across multiple services. Use password managers to store your credentials securely.

Technical Measures Against Phishing

Phishing-Resistant Multi-Factor Authentication (MFA):
This is a key security measure that mitigates the impact of password leaks and human errors, offering robust protection against phishing.
Regular System Updates:
Frequent updates help minimize the risk of exploiting known software vulnerabilities.
Antivirus and Anti-Malware Software:
Effective scanning prevents malicious files from causing harm before they get a chance to do damage.
Clear Security Policies:
Establishing security policies in compliance with the NIS2 directive and ISO 27001 standards protects company data and better prepares you for any incidents.
Security Monitoring:
Logging and analyzing events on servers and workstations allow for a rapid response in the event of an incident.

Why Is Phishing-Resistant MFA a Game-Changer?

Unlike password-only logins and traditional multi-factor authentication, which can be vulnerable to phishing, Rublon offers a truly phishing-proof platform, using authentication methods such as FIDO2 passkeys and FIDO U2F and FIDO2 security keys to effectively stop phishing attacks.

One of the most effective ways to protect against phishing attacks is to implement phishing-resistant multi-factor authentication (MFA).

Rublon’s multi-step authentication platform, based on the FIDO2 standard, can eliminate the consequences of phishing attacks.

Thanks to domain verification and the requirement of physically confirming the login process, a hacker who obtains the password still cannot access the account.

Why Consider Rublon MFA?

*A laptop protected by the Rublon MFA platform requires FIDO key authentication as the second factor.*

Here are the top reasons to consider Rublon MFA for combating phishing attacks, along with brief descriptions:

Complete Protection Against Phishing (Including Spear-Phishing and Whaling):
Even if a user falls for a phishing attempt, the FIDO2 security key verifies the domain’s authenticity and prevents completing login.
Minimizing the Impact of Human Error:
With phishing-resistant Rublon MFA, obtaining a user’s password is no longer a gateway to company resources.
Reducing Costs and Risks:
Effective protection against phishing means a lower probability of costly incidents, reduced downtime, fewer administrative penalties, and fewer reputational losses.
Easy Implementation:
Rublon MFA secures both on-premises systems (Windows, AD FS) and modern cloud services (email, web applications).
Compliance with Legal Requirements:
Regulations like the NIS2 directive mandate strong authentication methods. Rublon MFA ensures you meet these standards.
Scalability and Flexibility:
Rublon MFA is suitable for organizations of any size. You can begin by protecting your key assets and then gradually expand security to additional systems.
Expert Support:
Rublon MFA is not just a product; it also offers guidance on best practices, helping employees better understand the importance of MFA and speeding up its adoption across the organization.

An Opinion From Our Expert

We asked Michal Miszczuk, IT Security Specialist at Rublon, for his views on the practical importance of FIDO2 authentication in the context of rising phishing attacks:

“Today’s phishing campaigns are so sophisticated that they can fool even the most experienced users. From a security standpoint, it’s crucial to use solutions that protect employees from the consequences of human error. That’s exactly what using FIDO2 keys with Rublon MFA does. Domain verification and the need for physical confirmation of the login process effectively prevent hackers from taking over an account, even if the password has already been entered on a fake site.”
