The Top 11 Phishing Protection Solutions include:

Phishing protection solutions are a category of cybersecurity software designed to prevent phishing attacks. Since their conception, phishing attacks have evolved to become highly complex and targeted, allowing them to evade traditional email security gateways. As a response to this, email security providers developed a new type of solution dedicated specifically to phishing protection and the prevention of business email compromise (BEC): Integrated Cloud Email Security (ICES) solutions. 

Integrated cloud email security solutions sit within each user’s inbox and use machine learning to scan inbound and outbound emails—and sometimes other internal communications—for malicious activity. If the solution finds something suspicious—such as an unusual attachment type from an unknown sender, or an unusual request from a known user—the email is either removed, quarantines, or delivered with a warning banner explaining to the recipient about the potential risks associated with the email. 

Cloud email security solutions usually also include a “report phishing” plug-in that enables users to report phishing attacks directly from their inbox. The best solutions combine this functionality with phishing simulations that train users to identify and report phishing threats. Together the combination of technological and human-centric security creates the most effective barrier against phishing attacks.

In this article, we’ll explore the best phishing protection solutions. Some of the providers on this list combine cloud email security with phishing simulations; others extend their phishing protection beyond email to cover other communication channels, such as Slack and Teams. We’ll give you some background information on the provider and the key features of each solution, as well as the type of customer for which they are best suited.


IRONSCALES is the fastest-growing email security company in the world and the market leader in anti-phishing technologies. Their post-delivery protection solution offers protection against advanced phishing email threats like business email compromise (BEC), VIP impersonation, and Account Takeover (ATO). Their cloud-based solution is fully compatible with Office 365 and Google Workspace, meaning it is easy to deploy and does not require any MX record changes. Delivered as a comprehensive platform with a single admin dashboard, IRONSCALES’ solution provides security teams with the ability to detect and remediate phishing attacks.

IRONSCALES combines artificial and human intelligence to identify and automatically remove malicious emails in real-time. Once a suspicious event has been detected, IRONSCALES’ virtual security analyst (named Themis) detects and removes the threat from all impacted end-user inboxes, thereby reducing the workload of your busy security team. Each time this happens, the platform logs and remembers it so that the same attack can never infiltrate the network again.

IRONSCALES also allows end-users to report suspicious emails with a button directly inside their email inbox, regardless of whether they’re on desktop or mobile. When an end-user reports an attack in this way, all other users who have received the email will be notified with a customizable warning banner. Finally, they offer tailored, gamified phishing awareness training to teach users how to identify and report real-world attacks.

IRONSCALES’ complete solution is suited for organizations that need powerful, automated protection against phishing attacks.

Trustifi Logo

Trustifi is an email security an encryption provider that enable businesses to protect both their inbound and outbound communications against sophisticated email threats, including spear phishing and account compromise. Trustifi’s solution offers comprehensive security by combining outbound email encryption, which keeps sensitive data at rest, in storage and in transit safe from spying eyes, with inbound email security that scans inboxes for malicious content and blocks any threats. Trustifi deploys via API—requiring no MX record changes—and is fully compatible with local email clients, Office 356 Outlook and Google Workspace.

Trustifi’s Inbound Shield scans all inbound email communications for malicious content such as spam, phishing attempts and malware attachments, assigning each email a threat level and threat type. These range from “Authenticated”, meaning that an email is safe, to warning such as “Impersonation Attack” or “Spoofing Attack”, which warn that an email has been deemed dangerous. High-threat emails are either delivered with a warning, quarantined or blocked, according to admin-configured policies, ensuring malicious content never reaches its intended recipient. As well as configuring quarantine policies, admins can set up white- and blacklisting to prevent repeat attacks from known malicious senders, and to prevent trusted external senders from having their emails mistakenly quarantined.

As well as its inbound security, Tustifi offers AES 256-bit encryption for outbound emails that ensures all sensitive data is stored and sent securely. Recipients don’t have to have an account with Trustifi to decrypt emails, but admins can require that they must verify themselves via 2FA. This means that, if an inbox is compromised, the attacker won’t be able to access sensitive data by searching email content and they won’t be able to prove their identity.

Trustifi’s platform is praised for its ease of use, both from an admin and end user perspective. It comes with pre-configured setting to provide instant protection once deployed, before admins sign in to configure more granular email security settings such as email domain and file type blocking. We recommend Trustifi as a robust, user-friendly solutions for organizations trying to stop phishing attacks, and prevent bad actors accessing sensitive data in the case of successful business email compromise.

Microsoft Logo

Microsoft Defender for Office 365 (formerly ATP) is a cloud-based email security service that offers protection against unknown malware and viruses. Defender is included in some Exchange and Microsoft 365 subscription plans and is also available for purchase as an add-on module. Administrators can also use the inbuilt reporting and URL trace capabilities to gain insight into the kind of attacks that are occurring.

Defender’s anti-phishing solution uses machine learning modules to check inbound messages for key indicators that they may be a phishing attempt. These include the header, sender’s address and message content. When a threat is detected, the attack is blocked. Defender also has the capability to detect and block malicious links and attachments. This feature extends to protect SharePoint, OneDrive and Teams from malicious files, which many third-party solutions struggle to achieve.
