Best Phishing Protection Tools

Scott Pickard UPDATED: December 11, 2023

Protect your users from fraudulent email activity with these phishing protection tools

Integrating phishing protection tools into your environment is one of the most reliable and comprehensively secure ways to protect your email infrastructure. Phishing protection tools then use a range of mechanisms to keep your end users safe from phishing-related fraud. The most basic service they give is simply checking your inbound and outbound emails for dangerous content like predatory URLs or malware files. These technologies often interface with your system via a pre-defined setup for platforms like Office 365 or Google Workspace, or via an API with various integration options for your bespoke email system.

Other features could include phishing simulations, which send simulated phishing scams to your end users to assess their grasp of email security, which is a useful tool for educating your users about the risks associated with email communication.

Here is our list of the best phishing protection tools:

  1. Guardz – EDITOR’S CHOICE This cloud platform of security systems provides phishing protection and also blocks spam, malware, and impersonation scams. The package also includes a phishing simulator and user awareness training. Get a 14-day free trial.
  2. Avanan With its vast defense capabilities, the Avanan Cloud Security Platform is one of the most comprehensive cloud-based email security solutions on the market, ensuring the safety and compliance of your network's whole email infrastructure. The solution includes three distinct techniques for directly handling malware and anti-phishing attacks within the platform.
  3. Abnormal Security Abnormal may recognize instances in which a vendor has a high risk of fraud, indicating when an email should be thoroughly checked for signs of malicious behavior. Abnormal looks for deviations from the standard by analyzing massive amounts of data and building profiles of accepted behavior in your area.
  4. Trustifi Detects viruses that spread malware and ransomware, protects your email traffic from BEC attacks and switches authorized technicians using a great notification system. The system includes whitelisting and blacklisting options to boost overall security.
  5. Barracuda Sentinel The firm employs a ground-breaking API-based design that enables its AI engine to review previous emails and learn about customers' distinct communication habits. In the multi-layered email security system Barracuda Total Email Protection, Sentinel provides AI-based defense against spear phishing, account takeover, and hacked corporate emails.
  6. Proofpoint Essentials Delivers full protection against email-borne threats with a multi-layered anti-virus, anti-spam, and phishing detection engine. The system provides you with a sophisticated system interface to help you comprehend the entire hazard picture.
  7. BrandShield Offers a variety of specialized security solutions aimed at protecting the identities of your organization and its employees, one of which is its robust phishing protection solution.

A substantial amount of phishing protection tools marketed towards larger businesses cover a wider scope of features including email encryption technology. Email encryption systems secure your email data behind walls of protection to ensure only your intended destination receives the critical information held within email communications. Also, brand fraud detection systems that scan the internet to determine if your data has been compromised often go hand-in-hand with phishing protection tools. It is feasible that if your public data gets into the wrong hands, they may try to use your business identity against your own employees or customers to steal data and money.

More advanced modern systems employ machine learning and AI-driven systems to improve the security posture and usability of the product. They employ these systems to scan the activity of your users and monitor behavioral patterns—they can then compare this historical data to current behavioral patterns and quickly identify when an account is acting suspiciously.

The ultimate deciding factor in your chosen phishing protection tool is likely going to be the comparison of these extra peripheral features. All of the solutions on this list provide excellent phishing protection, but they all also provide a variety of different extra functions. Make sure you look through the article and check out which extra features sound useful to your business security.

The Best Phishing Protection Tools

1. Guardz – FREE TRIAL

Guardz Security Software

Guardz is a system-wide security monitoring service that is delivered from the cloud. The package protects endpoints and data held on cloud platforms with email scanning as one of its main defense mechanisms. The email protection system detects phishing attempts. It also identifies theft attempts that use impersonation, spam, and malware. This system is offered on a subscription.

Key Features:

  • Blocks malicious emails
  • Moves emails to quarantine
  • Option to restore
  • Delivered from the cloud
  • For Outlook and Gmail

The cloud-based scanner integrates into Microsoft Exchange Server/Outlook or Google Gmail through a plug-in. The system will move a malicious email to a quarantine area and post an alert in the management console. Technicians have the option to review a blocked email and restore it to the intended recipient’s mailbox if they have been flagged in error.

The Guardz package also includes a phishing simulator that helps to test the email filter. The simulator could also be used to educate users, but in that case, the security monitoring filter would have to be turned off. There is an extensive library of employee awareness training courses in the Guardz platform. An administrator can allocate a course to an individual or a group of users. The dashboard then tracks progress through the course and registers completion.

Guardz stresses that its system needs to be administered by a managed service provider (MSP). Companies that don’t have an agreement with an MSP in place can select one from the Guardz list of recommended suppliers. The top plan of Guardz is a managed security service.

The lower two plans of Guardz are subscription editions with a rate per user. There is no minimum team size for a plan, so the package will cater to even the smallest business. You can investigate Guardz further with a  14-day free trial.


Guardz is our top pick for a phishing protection tool because it provides full protection for an IT system against email-based attacks. As well as blocking phishing emails, this tool will filter out spam and identify theft attempts that involve manager impersonation. The tool also scans attachments for malware. Responses are automatic and involve moving suspicious emails to quarantine – they are not deleted and so can be restored. The plan is available for all sizes of businesses but it must be run by a managed service provider. The Guardz package includes a Dark Web scanner that alerts if company email accounts or up for sale on hacker forums. It also provides a phishing simulator and employee security awareness training.

2. Avanan


The Avanan Cloud Security Platform, with its extensive defense capabilities, offers one of the most comprehensive cloud-based email security solutions on the market, assuring the safety and compliance of your network's whole email infrastructure. The solution provides three unique procedures for managing malware and anti-phishing attacks directly within the platform. After an email is given to the user, the ‘Detect and Prevent' system checks it and corrects any problems before the transmission is complete. This technology makes certain that your end users are never exposed to potentially harmful attacks.

Key Features:

  • Security workflows
  • Detect and Prevent system
  • Quarantine Mailbox
  • In-depth alerting

Unlike a variety of other solutions, which exclusively secure incoming email, Avanan protects email in both directions (internal, external, outgoing), which provides total defense against all threats, including insider threats. Machine learning is used by the engine to create a profile based on past data such as login locations, data-transfer behavior, and email message partners. Search and Destroy enables security teams to swiftly identify the threat in a phishing attack that may have resulted in a breach. Admins can remove those emails from users' inboxes with a simple click, and email Recheck verifies harmful emails twice to ensure accuracy.

Deploy a cutting-edge security stack via the detect and protect mode, which provides an automatic policy action to quarantine malware, phishing attacks, and so on. You can set up a special quarantine mailbox to hold any emails or attachments that are quarantined during the scanning process due to policy or human activities.

Avanan offers a 14-day free trial of their services, during which you may test out features like configurable security workflows and fast deployment. The entire solution is divided into three distinct SaaS models, each with its own set of features and pricing.

Finally, the Complete Protection plan includes encryption and data loss prevention, which may be required for certain compliance needs; it costs $7.20 per user each month.

3. Abnormal Security

Abnormal Security

Abnormal may detect scenarios in which a vendor may provide a high risk of fraud, indicating when an email should be extensively examined for indicators of malicious behavior.

  • Behavioral analysis
  • Broad integrations
  • API deployment
  • Email automation
  • In-depth reporting

The technology is meant to interface with Microsoft 365 and Google Workspace fast and without disrupting mail flow, by connecting natively with these spaces to build a behavioral profile of your people, business, and vendors. Tens of thousands of indicators across identity, behavior, and content are evaluated for anomalies and malicious conduct, including never-before-seen attacks with no traditional indicators of compromise. To assist analysts in responding to security incidents, Abnormal also integrates with incident response protocols and tools. It initiates playbooks, generates tickets, and transmits logs and information to SOAR, SIEM, and ITSM platforms.

Abnormal produces automatic profiles of your personnel after integration to create baselines, secure your organization, and get you up and running rapidly. The software instantly identifies all the vendors in your ecosystem, allowing you to assess their level of risk. The solution centralizes data, insights, actions, and the management of global block lists across hundreds of tenants in a single location for both Microsoft and Google environments. Abnormal behavioral analysis algorithms may also work for its users, and the program learns their preferences when they move emails between folders in their mailbox.
