We live in a digital world and, as we become increasingly dependent on digital communication such as email, we become more vulnerable to cyber-attacks like phishing. Phishing is a type of cyber-crime based on email fraud. A bad actor disguises themself as someone trustworthy in order to trick their victims into giving them sensitive data such as usernames, passwords and financial information. Phishing emails can target hundreds or even thousands of people at once, and they’re one of the most common and financially dangerous online crimes that we see today.
In this article, we’ll explore the top ten solutions designed to protect your organization against phishing attacks. These include Secure Email Gateways, which filter dangerous emails before they reach the user’s inbox; post-delivery cloud email security solutions, which scan inbound and outbound emails for potential threats; and security awareness training platforms. One of the most useful forms of prevention is education; being aware of phishing attacks will make you less likely to fall victim to them. We’ll give you some background information on the provider and the key features of each solution, as well as the type of customer that they are most suitable for.
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.
Avanan offers cloud-based email and application protection against sophisticated phishing, malware, account compromise and data loss attacks. Designed to work with Office 365 and G Suite, you can deploy Avanan’s solution in minutes as an Office 365 app or configure it manually with a fast and simple deployment process. Once deployed, it offers security for all connected cloud-based applications like OneDrive, Google Drive and Teams.
Avanan uses machine learning technology to analyze email communication patterns, which allows their engines to detect user impersonation or fraudulent messages before they reach the inbox. It does this by identifying indicators of malicious emails, including the time and location of sending, domain and email content itself, to detect threats.
The fact that Avanan’s solution uses machine learning technology means that it’s constantly adapting to new and innovative attacks designed to slip past legacy email security solutions and gateways. It provides protection for each user’s individual inbox, rather than the organization’s general domain, which protects users from inbound, outbound and internal emails.
Avanan can identify malicious behaviour across the email network, from permission changes and files updates to internal messages sent via other cloud applications. This helps detect and flag compromised accounts, mitigating against business email compromise attacks.
Avanan deploys within your network environment in a matter of minutes and is designed to work well alongside other third-party security providers such as ATP. This makes it an ideal solution for organizations looking to reinforce their existing email security stack.
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 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.
However, Defender isn’t as effective as some of the other third-party solutions explored in this list. This is largely down to it being less mature than other protection methods; it doesn’t have the experience in adapting to threats that other solutions have acquired over time.
Microsoft Defender is popular for its cost-effectiveness and seamless integration with an Office 365 environment. This makes it suitable for any organization looking for a quick and easy-to-deploy security solution. However, for more advanced and effective protection, users should consider investing in a more powerful third-party solution.
