Top 10 Integrated Cloud Email Security Solutions For Business

Material Security provides a complete cloud workspace security platform for Google Workspace and Microsoft 365.

It tackles email, identity and data security threats across a multi-layered platform that provides inbound threat detection, account compromise protection, and automated threat response.

Detection And Response For The Full Cloud Workspace

Using deep API integrations, AI agentic automation and LLM analysis, and advanced threat research, Material’s cloud workspace security platform protects against inbound email threats like VIP impersonations, business email compromise and other sophisticated attacks

Material takes a unique approach by also protecting sensitive email content, like one-time passcodes and confidential files within the inbox itself. If an account is compromised, Material’s additional authentication workflows limit the blast radius and make sure sensitive email data is protected.

File security permissions controls and identity security controls extend that protection across the workspace — restricting what a compromised account can actually reach inside Google Workspace and Microsoft 365.

Material also delivers automated AI-powered OAuth app remediation, which monitors OAuth connections and revokes risky third-party tokens. This delivers insight into the OAuth connections to AI tools and third-party apps that most security teams have limited visibility into. Material deploys in under 30 minutes via API with no MX record changes required.

What Security Teams Say

Users of the service report that the account compromise protection features are highly effective, helping to slow down attacks and limit the amount of data that can be accessed.

Customers also highlight the automated remediation and phishing investigation capabilities as significant time savers for analysts. Reporting is straightforward, deployment is fast, and reviewers consistently note the pace of new feature releases and the responsiveness of the support team.

Some teams note that rules configuration can be challenging without in-house email expertise, but that the Material support team is responsive.

Our Take

Material Security’s strength is how it connects security capabilities across email and the entire cloud workspace. Inbound detection catches the threats that bypass native controls. Sensitive data protection ensures that what attackers are actually after — OTPs, confidential files, password reset links — is locked down regardless of how they got in. Identity controls contain the blast radius when an account is compromised. And the OAuth Threat Remediation Agent monitors and actively remediates third-party app connections across the workspace, addressing an attack surface most organizations have no visibility into at all. The result is a platform where a threat that slips past one layer runs into the next — rather than into open air.

If you have a lean security team that is looking for a dedicated security platform for M365 or Google Workspace that covers advanced email threats and secures against account compromise, this is a serious solution to consider.

Abnormal AI is a cloud-native email security platform that uses behavioral AI to catch threats traditional gateways miss. It targets Microsoft 365 and Google Workspace teams who want API-layered protection on top of their native security. The differentiator: it profiles sender behavior, not just message content.

Behavioral AI That Watches Senders, Not Subjects

The Inbound Email Protection engine builds a risk profile for every message. Safe mail lands in the inbox, spam goes to junk, and ambiguous emails arrive with a warning banner so users pause before clicking. Abnormal also rewrites URLs in suspicious messages to block phishing redirects.

We found the Account Takeover Protection module checks emails against 45,000+ compromise indicators, including login frequency, location, and communication patterns. When something looks off, it logs the user out, blocks access, and flags admins. That shuts down lateral spread fast.

What Customers Are Saying

Customers say setup runs fast, with some teams finishing 90% of configuration in a one-hour call with an Abnormal engineer. Many flag a sharp drop in phishing and credential theft after switching from older email gateways.

On the downside, users have flagged false positives. Legitimate emails, including invoices, sometimes land in junk. Some customers also say the AI Phishing Coach module still feels rough, with audio and video sync issues that signal early-stage quality.

Who Abnormal AI Fits Best

We think Abnormal makes most sense if your environment runs on Microsoft 365 or Google Workspace and you want layered protection that doesn’t fight your native controls. It sits at the premium end on price, but the account takeover engine and low admin overhead pay that back quickly for mid-market security teams.

IRONSCALES is a phishing-focused email security platform that pairs machine learning with crowdsourced human reporting. It targets Microsoft 365 and Google Workspace teams who want their users actively flagging threats from inside the inbox. The platform also extends to Teams and Microsoft Exchange.

AI Plus Crowdsourced Reporting in One Stack

Themis, the AI engine, auto-classifies suspicious emails for automated remediation, with warning banners on the borderline cases. Users report phishing with one click from Outlook. IRONSCALES then shares that intelligence across its network for faster collective detection.

We saw the platform pull double duty as security and awareness training, with built-in phishing simulations and remedial training tied to user behavior. DMARC management, internal email scanning, and Teams protection round out the package.

What IRONSCALES Users Flag

Customers say setup is fast, with some teams seeing IRONSCALES find threats during a 10-minute onboarding call. Many flag the simple three-button reporting model (Spam, Phishing, Safe) as a win for user adoption, and several have caught threats Microsoft Defender missed.

On the downside, users have flagged the lack of granular admin roles. Analysts need full admin rights to handle both remediation and training tasks. Some customers also say the DMARC module costs extra on top of the base subscription.

Where IRONSCALES Lands Best

We think IRONSCALES is a strong fit if your team runs Microsoft 365 or Google Workspace and you want users active in phishing defense. It’s less suited to organizations on legacy on-prem mail.

The combined inbox protection, simulation, and training stack saves time for lean security teams. API-based deployment means your existing controls stay in place.

Avanan, now part of Check Point, secures Microsoft 365 and Google Workspace email through API-based integration. It catches advanced phishing and account compromise threats before they reach the inbox, without requiring MX record changes. The platform also extends to Teams and Slack.

ML Detection That Layers on Native Email Security

The ML engine analyzes over 300 phishing indicators per message, scoring threats before they hit the inbox. We saw it focus on attacks that slip past traditional email gateways and Microsoft’s native defenses. Account compromise detection runs continuously inside the M365 environment for internal visibility.

Deployment runs through API rather than MX record changes, so Avanan layers cleanly on top of Microsoft Defender and Google’s native filtering. The platform also extends phishing and malware coverage to Slack and Teams, closing the gaps in collaboration tools.

What Avanan Customers Flag

Customers say setup runs fast, with some seeing immediate results without disabling Microsoft Defender or ATP. Many flag a sharp drop in phishing volume after switching from gateway-based tools, and several call out the DLP automation that flags outbound PII and PCI.

On the downside, users have flagged the lack of a mobile admin app for managing incidents on the go. Outside that, complaints are sparse, focused on minor admin friction rather than detection gaps.

Where Avanan Lands Best

We think Avanan makes most sense if your team runs Microsoft 365 or Google Workspace and you want phishing detection that works alongside your native security rather than replacing it. The Slack and Teams coverage adds value if collaboration tools are part of your threat surface.

The API-based deployment keeps your existing controls intact, and the platform’s strength sits squarely with phishing and account compromise.

Darktrace Email is an AI-driven email security platform that builds behavioral baselines for every user to spot anomalies. It protects Microsoft 365 and Google Workspace teams against phishing, BEC, supply chain attacks, and accidental data loss. The platform also extends coverage to wider SaaS environments.

Behavioral Baselines for Every User

The AI engine builds a normal pattern for each employee and flags anything that breaks from it. We saw it cover the usual phishing and malware ground while catching subtler issues like BEC and supply chain attacks. The system blocks harmful elements automatically and tells users why content disappeared.

Beyond inbound threats, Darktrace flags accidental data loss before it happens. We found it catches misdirected emails, wrong attachments, and other insider mistakes traditional filters miss. SIEM integration and SaaS coverage round out the platform.

Darktrace in Production

Customers say the AI adapts well, with low false positives after the baseline settles in. Many flag the search interface as fast and clear, with email tracking taking seconds. The AI phishing simulation that crafts tests from real inbox data also gets praise.

On the downside, users have flagged that the journalling-based deployment causes friction with other security integrations. Some customers also say pricing sits at the higher end, though most see proportional value.

Where Darktrace Email Lands Best

We think Darktrace Email makes most sense if you have a mature security team that wants AI-driven anomaly detection layered on Microsoft 365 or Google Workspace. The behavioral baseline approach pays off most when your organization has predictable communication patterns to learn from.

If you’re running multi-tenant or hybrid environments, the API deployment and SaaS coverage extend protection past the inbox cleanly.

Egress Protect is an ICES platform that uses machine learning to spot phishing and BEC attacks based on context, not just content. It targets Microsoft 365 teams who want warning banners and admin insights on at-risk accounts. The wider Egress suite also covers outbound DLP and AES 256-bit encryption.

Context-Aware Phishing Detection

The detection engine looks beyond malicious links and attachments. We saw it analyze tone, urgency, and contextual signals to flag phishing attempts without obvious payloads. The platform places warning banners on suspicious messages, and admins see which accounts trigger the most flags.

The wider Egress suite extends into prevention. Egress Prevent catches misaddressed emails and wrong-recipient mistakes before they leave the outbox, and DLP rules layer on top for insider risk control. AES 256-bit encryption with push or pull delivery handles sensitive outbound communication.

What Egress Customers Are Flagging

Customers say setup is fast and the Outlook plugin makes training simple. Many flag the warning banners as effective at catching errors before they cause damage, and several call out responsive support and friendly account management.

On the downside, users have flagged that the encryption portal workflow gets clunky for external recipients. Some customers say replies through the secure portal involve multiple logins and limited search. Per-license costs also add up quickly at scale.

Who Egress Protect Fits

We think Egress Protect makes most sense if you run Microsoft 365 and want context-aware phishing detection paired with outbound DLP in one platform. We found the detection engine and admin insights cover BEC and tone-based attacks well.

The encryption portal works best for occasional sensitive transmissions, not daily external communication. For teams that fit, the integrated suite offers strong end-to-end coverage.

Inky is a cloud-based email security platform built around customizable warning banners and ML-driven phishing detection. It targets Microsoft 365 and Google Workspace teams that want clear user-facing signals on every inbound, internal, and outbound message. The platform analyzes how users write to spot impersonation attempts.

Banners on Every Email, Including Internal

Inky places customizable banners on every email, marking it safe, potentially malicious, or harmful. Admins choose whether to auto-quarantine flagged messages or let users decide. We saw the platform scan inbound, outbound, and internal email together.

The ML detection includes a writing style analysis that learns how each user composes messages. We found this useful for catching impersonation attempts where the content looks reasonable but the linguistic fingerprint is off. Inky layers cleanly with EOP or a SEG.

What Inky Customers Are Flagging

Customers say the banners drive real user awareness, especially on edge cases like spam and gray mail. Many flag the AI writing style detection as a strong differentiator, and several call out low admin overhead once the platform is running.

On the downside, users have flagged the Google Workspace setup as painful. Some customers say onboarding takes longer than expected and end-user client setup adds friction. A few also flag that banners stick around even after a sender is tenant-approved.

Inky’s Sweet Spot

We think Inky makes most sense if you’re running Microsoft 365 and want banner-driven user awareness layered on top of EOP or your existing gateway. The writing style analysis adds real value for organizations dealing with impersonation attempts and BEC.

Google Workspace deployments take longer to set up. Once running, the low admin overhead and clear user signals pay off across the longer term.

Mimecast Integrated Cloud Email Security is a Microsoft 365-focused email security platform from a long-established vendor. It targets US and UK organizations that want AI-powered phishing and malware detection layered on native M365 controls. The platform pulls threat intelligence from over a billion daily emails.

Threat Detection Backed by Scale

The ML detection engines pull from over a billion emails inspected daily, which feeds body and subject analysis, attachment scanning, and impersonation detection. We saw the platform layer in end-user reporting alongside automated controls, giving security teams more signal without more noise.

The threat dashboard explains the reason behind each blocked email, with full risk assessment visibility per message. Contextual warning banners update in real-time across inboxes and devices, so users see consistent signals whether they’re checking Outlook, Teams, or mobile.

What Mimecast Customers Are Flagging

Customers say spam filtering is intuitive and reliable, with daily “on hold” summaries reducing moderation work. Many flag the rule configurability as a strong point. Admins build custom phishing rules and department filters quickly, and URL protection extends into Teams.

That said, users have flagged the lack of API integration as a limitation. Some customers say the MX-based deployment makes it harder to feed metrics into SIEM platforms or correlate threat data with the wider security stack.

Who Mimecast Fits

We think Mimecast makes most sense if your organization runs Microsoft 365 in the US or UK and values established threat intelligence over API-first architecture. The scale of inspected emails feeding the ML engines creates real detection depth.

If your security stack relies heavily on SIEM integration, the gateway-based architecture trades flexibility for proven scale. Teams running mature mail flows benefit most from the configurability.

PhishTitan, from TitanHQ, is a cloud-based email security platform built specifically for Microsoft 365. It catches phishing, malware, and credential-based threats that slip past Microsoft’s native filters. The platform deploys through API integration without disrupting existing M365 controls.

Phishing Detection With Single-Click Cleanup

The AI engine analyzes inbound emails for phishing patterns, with link lock service scanning URLs in real-time when users click them. We saw the in-line warning banners flag suspicious messages directly inside the inbox, with admins running single-click remediation across affected accounts when something gets through.

The platform layers DLP, smart mail protection, and curated threat intelligence on top of the core detection stack. Reporting covers inbound email threats and user behavior patterns, giving admins visibility into how the platform performs over time.

What PhishTitan Users Flag

Customers say PhishTitan handles day-to-day phishing well and the support team delivers reliable help when issues come up. User-based phishing reporting also draws praise, fitting cleanly into M365 workflows.

The PhishTitan-specific review pool is thin, and some customer feedback covers training and simulation features from other TitanHQ products. Some users have flagged a steep learning curve for security teams new to phishing tools, with training programs recommended before rollout.

Who PhishTitan Suits

We think PhishTitan makes most sense for SMBs and mid-market organizations on Microsoft 365 that want focused phishing and malware protection without enterprise-tier complexity. The API deployment slots in alongside Microsoft Defender without disrupting your existing controls.

At enterprise scale with mature security stacks, feature depth runs lighter than enterprise-focused competitors. If your team needs clean, targeted phishing defense for M365, the platform earns its place.

Trustifi is a cloud-based email security and encryption platform that protects against inbound threats while making compliance-grade encryption simple for outbound messages. It targets Microsoft 365 organizations dealing with sensitive data, including HIPAA-regulated environments. The platform also extends to Google Workspace, with strong multi-tenant support for MSPs.

Inbound Shield Plus One-Click Compliance

The Inbound Shield scans email content in real-time, catching malicious links, harmful attachments, phishing, spoofing, and BEC attempts. We saw the centralized admin dashboard pull these controls together, with customizable policies and granular quarantine review.

On the outbound side, the platform auto-encrypts sensitive content with a One-Click Compliance trigger for regulated workflows. We found the recipient experience clean: encrypted emails arrive in the inbox with two-step verification handling authentication. DLP rules and account takeover protection round out the stack.

Trustifi in Daily Use

Customers say setup is fast and the platform handles M365 and Google Workspace cleanly. Many flag the AI-based filtering and easy DLP rules as standouts, and several call out responsive support across standard and MSP deployments. Pricing comes up as competitive.

On the downside, users have flagged that quarantine notifications to end users feel overwhelming, with limited options to disable them. Some customers say the threat simulation feature feels lighter than dedicated awareness platforms.

Trustifi for Compliance Teams

We think Trustifi makes most sense if your team runs Microsoft 365 or Google Workspace and needs easy-to-use encryption alongside inbound protection. The HIPAA and compliance workflows pay off particularly well for healthcare, legal, and financial services teams.

For MSPs managing multiple tenants, the multi-tenant filtering and central dashboard make management lighter. The combination of inbound security and outbound encryption in one platform keeps your stack consolidated.
