Top 10 Anti-Phishing Tools for 2023

Top 10 Anti-Phishing Tools for 2023

Imagine arriving at work one day only to find that your organization’s critical data is now in the hands of cyber attackers. That’s highly likely, considering that more than 255 million phishing attacks were detected over six months in 2022.

The previous year saw email phishing attacks increase by 667% despite growing awareness and prevention efforts. When major companies such as OpenSea and MailChimp fall victim, resulting in the loss of millions of dollars and the exposure of thousands of users’ private data, one must wonder: am I next? 

Understanding phishing and the tools that can help prevent it is critical, as organizations of all sizes are equally at risk. In this article, we explore what anti-phishing tools are and how they help fight against phishing scams.

What Are Anti-Phishing Tools and How Do They Work?

Anti-phishing tools are designed to protect individuals and organizations from phishing attacks by automatically identifying and blocking suspicious activity, links, attachments, and messages. Typically, the following solutions are categorized as anti-phishing tools:

  • Email filters analyze multiple aspects of an email, such as sender, subject line, content, attachments, and embedded links, to identify threats, mark suspicious emails as spam, and delete or block them.
  • Anti-virus software can help to identify and block malicious attachments or links in emails that lead to phishing websites. It uses signature-based detection to match known threats and heuristics to identify new, unknown threats. It can also scan incoming emails for malware or other malicious code that may be used in phishing attacks. 
  • Two-factor authentication (2FA) adds a layer of security to the login process by requiring users to provide two forms of identification to access their account (say, a password and biometrics). This makes it harder for an attacker to gain access to an account even if they’ve obtained the user’s password, helping to prevent impersonation, a common technique used in phishing attacks. 
  • SMS-based authentication is a type of 2FA that uses text messages sent to a user’s phone to add a layer of security to the login process. It requires users to enter a unique code sent to their mobile device and a password to access their account. 
  • Browser extensions use databases of known phishing sites and heuristics to analyze websites in real time and determine if they’re safe to visit. It warns users when they navigate a potentially malicious site so they can exit it before entering sensitive information, making a fraudulent transaction, clicking on a malicious link, or downloading a suspicious attachment.
  • Firewalls control network traffic to prevent unauthorized access to a network. They can be configured to block incoming and outgoing traffic based on criteria such as source IP address, destination IP address, and port number. By blocking traffic from known phishing domains or IP addresses, firewalls can help prevent them from reaching end users. 
  • Security awareness training educates employees on how to identify and avoid phishing attempts. Typically, it focuses on how phishing scams work, how to recognize phishing emails and avoid suspicious links or attachments, and how to protect sensitive information through safe online habits such as using strong passwords and 2FA.

Why Is Phishing Successful, and How Can the Right Tools Stop Attackers in Their Tracks?

Although anti-phishing tools can help, they are not foolproof. For example, SMS-based authentication is vulnerable to certain attacks, such as SIM swapping, where an attacker can obtain control of a victim’s phone number and intercept their SMS messages.

Firewalls, email filters, and anti-virus software alone are also insufficient to fully protect against phishing. Although they help block malicious technology, these attacks often use social engineering tactics to trick victims into providing sensitive information. 

For example, to convince victims to hand over sensitive information, spear phishing is customized to target specific individuals or types of employees, while whaling phishing is highly personalized to target high-level executives. Email filters may deter some of these messages but won’t work in the case of an account takeover because the sender will technically be legitimate. 

Meanwhile, anti-virus software can help protect against phishing attacks that deliver malware through email attachments or web downloads. Still, it can’t effectively protect users against attacks that don’t involve malware. Similarly, firewalls cannot defend against social engineering attacks by focusing only on the network layer and can be bypassed if attackers find a weakness in the firewall’s configuration or exploit a vulnerability in a network.

Additionally, these software, alongside browser extensions, focus on detecting and removing known malware and phishing attempts. But phishing attacks are constantly evolving and adapting, making it difficult for anti-phishing software to keep up with the latest threats. Attacks that haven’t been added to the software’s database of known threats will pass by undetected.      

Ideally, anti-phishing software can serve as an awareness tool for training users to recognize phishing scams autonomously. In a company setting, this helps them to proactively alert the rest of the team or report the attempted attack to the security department for further investigation. But human error still happens even among well-informed employees. 

Additionally, corporate security awareness initiatives don’t protect end users outside the company’s perimeter. Without the same level of security awareness or technical knowledge as employees, customers become easier targets for phishing scams, which cause much damage to the reputation of brands being impersonated. Besides, phishing attacks can also be launched on customers to gain access to corporate systems–for example, through credential theft, malware, supply-chain attacks, and account takeover.

As a result, phishing attacks continue to succeed, and their consequences can be severe. One common immediate impact is financial since attackers often steal sensitive information such as credit card numbers or login credentials to victims’ online banking apps or trick victims into conducting fraudulent transactions, costing Americans over $40 billion in 2022

Additional consequences include compromising sensitive business information, leading to loss of customer trust and further long-term losses due to reputational damage. 


Key Features to Look for in an Anti-Phishing Tool 

With this in mind, specialized anti-phishing software should ideally have a combination of all the following capabilities:

  • Real-time detection and blocking of phishing attempts by continuously analyzing incoming emails and web traffic
  • ML-based analysis to identify phishing attempt patterns
  • Browser extension or plugin that warns users when visiting a potentially malicious domain
  • Deny lists and safe lists: The software should maintain and continually update a database of known phishing sites and email addresses
  • Education and training for users beyond the corporate perimeter so they can avoid and report phishing attempts
  • Integration with other security systems to provide a comprehensive security solution
  • Detailed reports and analytics on phishing attempts, including the attack’s origin, the type of attack, and the target
