Why Choose
IRONSCALES over Mesh Security
When selecting an email and messaging security platform, it's crucial to consider not only the features but also the experience and history behind the technology. IRONSCALES, with over a decade of innovation in email security, has been at the forefront of integrating AI and machine learning into its solutions long before these technologies became industry standards.
This page compares IRONSCALES with Mesh Security, a newer entrant to the market that launched in 2021, to help you choose the right platform for your organization.
For Managed Service Providers (MSPs), IRONSCALES offers mature, time-tested solutions with streamlined integration, centralized management, and optimized pricing models with monthly billing, making it the ideal choice for managing multiple clients efficiently.



IRONSCALES is a pure ICES platform, integrating natively with Microsoft 365 and Google Workspace via API-only connections. Leveraging NLP and NLU, IRONSCALES creates baselines and social graphs, analyzed by Adaptive AI to detect subtle anomalies and threats. The platform offers AI-based automated remediation and continuously evolves through insights from over 15,000 global organizations and 25,000+ analysts.
Additionally, IRONSCALES includes integrated phishing simulation testing, security awareness training, dynamic alert banners, and report phishing buttons with GenAI Copilot for Outlook. For MSPs, this means speedy, hands-free deployments, centralized management, and customizable security solutions tailored to each client’s needs— with minimal management overhead.

Mesh is a relatively new entrant in the email security space, having launched in 2021. The company offers a two-pronged approach to email protection with its Mesh Gateway (SEG) and Mesh 365 (API). Mesh Gateway focuses on perimeter security, blocking threats before they reach the network, while Mesh 365 enhances this protection with API-based integration and machine learning to address phishing threats and BEC attacks.
Despite its innovations, Mesh is still evolving and lacks features like NLP, NLU for creating detailed baselines and social graphs, integrated report phishing buttons, a GPT-powered virtual email assistant (like Themis Copilot for Outlook), and comprehensive phishing simulation and security awareness training, which are standard in IRONSCALES.
Navigating the Shifting Landscape of Email Security
Email security has transformed significantly over the past two decades. Traditional methods like authentication and signature-based secure email gateways (SEGs) can no longer keep up with modern attackers. Today, email security must proactively address "malicious intent" such as social engineering and automate email incident remediation.
Modern solutions leverage AI, machine learning (ML), automation, and human insights to tackle advanced threats like Business Email Compromise (BEC), Account Takeover (ATO), and VIP impersonation. For MSPs, staying ahead of these threats means choosing a solution that integrates seamlessly, reduces incident management burdens, and offers flexible pricing options.
Both Mesh and IRONSCALES offer solutions to address this evolving threat landscape, with IRONSCALES drawing on over a decade of innovation to deliver a mature, comprehensive platform. Let’s start with a comparison of their features.

How are IRONSCALES and Mesh Solutions Different?
IRONSCALES is a mature, AI-driven ICES platform, seamlessly integrating with Microsoft 365 and Google Workspace through API-only connections. With over a decade of experience, IRONSCALES utilizes advanced NLP and NLU to build detailed baselines and social graphs, allowing Adaptive AI to detect subtle anomalies and threats. The platform offers automated threat remediation and continuously evolves with insights from over 15,000 global organizations and 25,000+ analysts. IRONSCALES also includes integrated phishing simulation testing, security awareness training, dynamic alert banners, and a GPT-powered email assistant, Themis Copilot for Outlook. For MSPs, this means streamlined deployments, centralized management, and customizable security solutions tailored to client needs with minimal management overhead.
Mesh Security entered the market in 2021 and offers a combination of Mesh Gateway (SEG) for perimeter defense and Mesh 365 (API) for advanced threat detection. While Mesh 365 integrates with Microsoft 365 and uses machine learning, it lacks the comprehensive NLP, NLU capabilities, and employee empowerment features provided by IRONSCALES. Mesh does not offer integrated phishing simulation testing, a security awareness training platform, or an advanced virtual email assistant like Themis Copilot for Outlook. As a newer player, Mesh’s solutions are evolving, but they don’t yet match the breadth and depth of protection offered by IRONSCALES.
For businesses seeking a comprehensive email security solution that combines the best of AI and human insights, IRONSCALES remains the clear choice.
