Abnormal Security Review: a comprehensive email security solution that uses AI and machine learning

In 2025, it is essential for companies to have a comprehensive email security solution. These protect one of the most vulnerable and widely used communication channels in the corporate environment: emails.

With a landscape full of threats such as phishing, malware or business email compromise (so-called BEC attacks), it is imperative to find a service to protect our company's mailboxes. But... what tool is right for our business?

To help you decide which security tool to install in your company, we offer you a review of Abnormal Cloud Email Security, one of the best tools for companies seeking a comprehensive email security solution with integrated AI.

Why is it important to implement an email security solution for your company?

Through email, hackers can launch all kinds of attacks (phishing, malware, BEC, ransomware, and other threats), which can have serious consequences such as the loss of confidential information, operational disruptions, and damage to your business’s reputation.

By implementing a powerful security solution, companies can detect and block these threats before they reach the end user, thus significantly reducing the risk of cybersecurity incidents.

Furthermore, a comprehensive solution not only filters malicious messages but also offers advanced tools such as authentication, encryption, behavior analysis, and protection against identity spoofing (spoofing).

Abnormal Security: What it is and what it is for

Abnormal Security is an advanced email security platform based on artificial intelligence (AI) that protects organizations against sophisticated threats such as phishing, identity spoofing, and account takeover

Founded in 2018 with an impeccable track record, the company has developed a solution that analyzes user behavior to detect anomalies and prevent attacks that could bypass traditional defenses.

The platform uses human behavioral factors to understand communications and processes within an organization. By employing machine learning techniques and natural language processing, Abnormal Security examines the content of emails, establishes comparisons with historical behaviors, and continuously assesses the risk of suspicious activity on accounts.

In addition to detecting and blocking incoming attacks, Abnormal Security aims at protection against account takeover and continuously evaluates the risk associated with third-party access. Added to this is an API-based architecture that allows seamless integration with cloud email platforms, providing uniform defense across all communication channels and cloud ecosystems.

Audience: Who is Abnormal Security for?

Now that we know Abnormal Security in depth, it's time to ask if it is the cybersecurity solution your SMB needs for its email segment. To resolve your doubts, we have made a list of the types of users who can benefit from this platform. They are as follows:

• Multinational corporations: Due to their email volume, multiple locations, and high risk of targeted attacks.
• Financial sector companies: Such as banks, insurers, and fintechs, which handle extremely sensitive information.
  Healthcare institutions: That must protect confidential patient data and comply with regulations like HIPAA.
• Technology and software companies: That are frequent targets of attacks due to their digital infrastructure.
• E-commerce companies: To protect transactions, customer data, and prevent email fraud.
• Logistics and transportation companies: That can be attacked with fake orders, invoices, or operational instructions.
• Governmental organizations or public institutions: That are often targets of cyberattacks for political or economic reasons.

Why users switch to Abnormal Security

Users decide to switch to Abnormal Security mainly because of its innovation and its ability to detect and block sophisticated threats that other traditional solutions fail to identify.

Abnormal uses artificial intelligence and behavioral analysis to identify anomalies in email usage, allowing attacks to be stopped before they cause damage. This proactive protection is one of the most valued reasons by security and IT teams.

Additionally, many organizations make the switch seeking a more streamlined integration experience and simpler management. Abnormal Security integrates natively via API with platforms like Microsoft 365 and Google Workspace, without the need for additional hardware or complex infrastructure changes.

This reduces operational costs, improves efficiency, and accelerates deployment time. It also offers a clear interface and automated tools that simplify incident response, allowing teams to focus on strategic tasks rather than just putting out fires.

According to users, it is an attractive option for individuals and organizations looking to raise their security level without unnecessary complications.

Why Some Users Leave Abnormal Security

Some customers decide to leave Abnormal Security mainly due to the high cost compared to other market solutions. Although it offers advanced technology, for small and medium-sized businesses it can be difficult to justify the investment, especially if their threat exposure level is not very high or if they already have other security tools included in more affordable suites.

In some cases, the return on investment is not clear enough, leading organizations to choose a more affordable direction or one integrated with their current platforms.

Another reason for leaving may be related to the learning curve and internal adaptation. Despite its intuitive design, some companies find that it requires an initial adjustment phase and staff training to fully leverage its potential.

Additionally, as the solution is very focused on the email environment, some companies seeking broader coverage — including endpoints, networks, or other system layers — may prefer more comprehensive or integrated platforms that address multiple attack vectors from a single panel.

In summary, although Abnormal Security offers advanced protection, some customers leave it for reasons of cost, limited focus on email, or because their needs change and require a more generalist tool or one adjusted to smaller budgets.
