Best for: Businesses of all sizes that want 24/7 expert eyes on their identities

Huntress Managed ITDR is built to stop hidden threats like business email compromise (BEC) and session hijacking across the 16M+ identities we monitor today. These are some of the most damaging types of phishing attacks because they let bad actors quietly impersonate trusted users and sneak through your environment.

We go beyond reactionary phishing prevention software as a CVE Numbering Authority (CNA), our threat research doesn't just react to known attacks, it helps define them. We’re a team of human experts who watch your Microsoft 365 environment around the clock. If an attacker tries to use a rogue app to get into your system, we give you a clear, actionable report so you can shut it down immediately.

Our Managed Security Awareness Training (SAT) complements ITDR by turning your employees into a defensive layer. This training uses story-based episodes and realistic phishing simulations backed by real-world threat intelligence for personalized coaching. 

We also use the real attacks that our SOC analysts see across millions of identities to keep your training relevant and your environment secure with a 98% completion rate among employees who start a course.. Huntress is the only solution on this list that combines managed ITDR and Managed SAT in a single platform and it's backed by a 4.9/5 rating on G2 from 800+ reviews.

Pros & cons

Even the best tools can’t fully protect a team that’s rushed or distracted. You should share clear, repeatable behavior guidelines so employees know what safety should look like in their day-to-day workflows.

Five tips for all employees to follow:

1. Hover over links before clicking to verify the true destination, especially in invoices, urgent password messages, or unexpected file-share requests.

2. Treat any urgent or secret request for information as suspicious. Validate it with a second channel, like a phone call or chat.

3. Check sender details carefully, including the full email address and domain. Be wary of lookalike domains that swap or add characters.

4. Report anything suspicious immediately instead of deleting it, so your security team can remove similar messages from other inboxes.

5. Avoid reusing passwords across accounts. Enable password managers and multi-factor authentication (MFA) wherever possible.

What IT teams can do to prevent phishing

On the technical side, security teams can harden their environment so fewer dangerous messages ever reach end users.

Technical and security measures for IT teams:

• Enforce strong authentication with phishing-resistant MFA for high-value accounts and remote access.

• Deploy modern email security tools that scan URLs and attachments in real time and offer impersonation and BEC protections.

• Monitor identities and sign-in behavior continuously to detect session hijacking, rogue applications, and suspicious mailbox rules.

• Implement least privilege for email and SaaS access to prevent a compromised account from affecting your entire environment.

• Integrate a security awareness training program with your detection stack, so reported messages automatically feed into investigation and response workflows.

Organizations that pair strong user education with always-on technical monitoring close many of the gaps left open by traditional email filters. A managed cybersecurity partner like Huntress lets you focus on operations while specialists handle the noisy, fast-moving phishing landscape around the clock.

The best phishing protection software guards the identities that run your business. While software can help, having a managed partner means you don’t have to be the one waking up at 2am to deal with a compromised account.

Combining Huntress Managed ITDR with our Managed SAT gives you a defense that operates at two levels. Our security experts are always on the lookout, while your employees receive the coaching they need to identify threats before they reach us.
