While organizing email security solutions into categories can help security teams understand the types of products available, it can also lead to generalizations that overlook important differences within those categories and can become like comparing apples to oranges.

This is true for the Integrated Cloud Email Security (ICES) category. Among the products that qualify, there are important variations in approach that can mean the difference between stopping a novel phishing attack on the first encounter and catching it as many as 13 days later.

These distinctions highlight that not all ICES products and not all AI tools are made equal, and it’s critical to look deeper than the “ICES” label when examining an email security solution. 

What is an ICES solution?

Gartner devised the term ICES in 2021 to describe an advanced email security that augments the native capabilities of email providers by using API access to analyze email content without requiring changing the MX record. 

In other words, ICES solutions integrate with an organization’s cloud email provider to filter out malicious emails.

ICES has risen in popularity as more and more organizations shift to cloud-based or hybrid email servers, and encounter new, more sophisticated threats. Organizations pair ICES with improved native capabilities of email providers. For example, in the 2023 Market Guide for Email Security, Gartner acknowledged that “Microsoft, in particular, continues to make significant investments in improving protection effectiveness and providing better configuration guidance.” 

Native capabilities can detect traditional indicators of compromise, while ICES products can detect nuanced attacks. They integrate directly with cloud-based email providers, meaning emails do not have to be rerouted for analysis, therefore reducing the time security teams would have to spend configuring and maintaining that connection or risking operational outage. 

ICES protects against sophisticated attacks

Before the rise of ICES, the mainstream email security solutions were Secure Email Gateways (SEGs), which can be characterized as tools that rely on historic data to create rules and signatures. This purely reactive approach cannot contend with the current email threat landscape, which includes attacks that abuse legitimate services, originate from compromised known senders, or are entirely novel. They also struggle to detect multi-stage attacks and insider threats

Instead, ICES products use natural language processing and natural language understanding to identify social engineering like business email compromises, spoofing, supply chain attacks, account takeovers, and more.  However, although ICES products can detect more sophisticated threats than SEGs, not all of them can stop entirely unknown attacks. 

Achieving bespoke security with AI that understands you

Even though several ICES products rely on machine learning to identify and stop malicious emails, not all AI is the same. Typically, other vendors’ AIs are trained on insights pulled from across their respective customer-bases and past attacks. However, this does not account for nuanced distinctions that arise from organizations’ sizes, industries, or even the individual employees working at each company. 

Instead, Darktrace understands you. Self-Learning AI™ focuses on the organization it is installed in, instead of generalizing across a wider pool. Darktrace even learns on a granular level, building profiles of every individual employee by analyzing behaviors like how they typically communicate, where and when they log in, the tone and sentiment of their emails, file and link sharing patterns, and hundreds of other signals. This level of specificity ensures that the email security is tailored to each specific organization. 

The ability to learn employee behavior allows Darktrace to detect what is not normal, therefore revealing sophisticated threats on the first encounter. It can detect all types of attacks, including BEC, account takeover, insider threat, compromised internal accounts, and even human error. 

But it’s the ability to stop novel attacks upon the first encounter that sets it apart. Darktrace/Email™ can detect novel email attacks an average of 13 days earlier than email security tools that are trained on knowledge of historical threats. 

Moreover, Darktrace can take precise action to respond to threats, beyond simply allowing or blocking a suspicious email. The AI makes micro-decisions to neutralize only the malicious components of emails. For example, it might flatten an attached PDF, rewrite a shared link, or file an email as junk. 

Darktrace/Email goes further than other ICES by considering the employee experience. With an employee-AI feedback loop, the AI can fine-tune security based on the employees while also providing inline security awareness training in real-time and with real-life examples. By engaging down to the employee level, Darktrace AI can even leverage personalized insights for productivity gains, sorting out graymail based on how each user prefers to interact with it. 

Putting the “I” in “ICES”

Many ICES vendors emphasize the “integrated” part of the acronym, however Darktrace excels at this. Since Darktrace can be installed anywhere a company has data, it can natively interact across the digital estate, saving the security team time and resources otherwise spent learning various dashboards and languages, correlating data across different areas, and manually monitoring daily activity. Darktrace/Email can also integrate with external tools, including SIEMs and SOARs, to further enhance workflows

Moreover, since combining ICES solutions with native security email capabilities creates a hardened security posture, Darktrace/Email benefits from its strong, established integration with Microsoft

Introducing flexibility to ICES deployments

Finally, the security and integration capabilities of Darktrace/Email deploy easily. In the 2023 Market Guide for Email Security, Gartner predicted that “by 2025, 20% of anti-phishing solutions will be delivered via API integration with the email platform, up from less than 5% today.” Darktrace/Email can be rolled out via API or API + Journaling in Microsoft 365, whichever better fits the organization’s needs.

While all ICES products are API-based, that does not mean they are AI-first, or are using the best AI approach. Even some SEGs can deploy via API. That means that the ability to deploy via API does not guarantee a level of security that can stop the most sophisticated threats. Security teams should look beyond deployment method and select the ICES and AI solutions that provide tailored, effective security. 

Finding nuance as an ICES solution

Email security continues to advance in tandem with the threat landscape and organizations’ digital infrastructures. ICES solutions are supplanting SEGs as the mainstream email security solutions, however that broad category includes a range of tools with varying applications of AI. These differences make it critical to not put all ICES products in the same basket. 

Darktrace/Email is the only ICES solution that uses Self-Learning AI to detect all types of email threats, including novel attacks, within seconds.

Resilience at the Speed of AI: Defending the Modern Campus with Darktrace

Default blog imageDefault blog image

Why higher education is a different cybersecurity battlefield

After four decades in IT, now serving as both CIO and CISO, I’ve learned one simple truth: cybersecurity is never “done.” It’s a constant game of cat and mouse. Criminals evolve. Technologies advance. Regulations expand. But in higher education, the challenge is uniquely complex.

Unlike a bank or a military installation, we can’t lock down networks to a narrow set of approved applications. Higher education environments are open by design. Students collaborate globally, faculty conduct cutting-edge research, and administrators manage critical operations, all of which require seamless access to the internet, global networks, cloud platforms, and connected systems.

Combine that openness with expanding regulatory mandates and tight budgets, and the balancing act becomes clear.

Threat actors don’t operate under the same constraints. Often well-funded and sponsored by nation-states with significant resources, they’re increasingly organized, strategic, and innovative.

That sophistication shows up in the tactics we face every day, from social engineering and ransomware to AI-driven impersonation attacks. We’re dealing with massive volumes of data, countless signals, and a very small window between detection and damage.

No human team, no matter how talented or how numerous, can manually sift through that noise at the speed required.

Discovering a force multiplier

Nothing in cybersecurity is 100% foolproof. I never “set it and forget it.” But for institutions balancing rising threats and finite resources, the Darktrace ActiveAI Security Platform™ offers something incredibly valuable: peace of mind through speed and scale.

It closes the gap between detection and response in a way humans can’t possibly match. At the speed of light, it can quarantine, investigate, and contain anomalous activity.

I’ve purchased and deployed Darktrace three separate times at three different institutions because I’ve seen firsthand what it can do and what it enables teams like mine to achieve.

I first encountered Darktrace while serving as CIO for a large multi-campus college system. What caught my attention was Darktrace's Self-Learning AI, and its ability to learn what "normal" looked like across our network. Instead of relying solely on static signatures or rigid rules, Darktrace built a behavioral baseline unique to our environment and alerted us in real time when something simply didn’t look right.

In higher education, where strict lockdowns aren’t realistic, that behavioral model made all the difference. We deployed it across five campuses, and the impact was immediate. Operating 24/7, Darktrace surfaced threats in ways our team couldn’t replicate manually.

Over time, the Darktrace platform evolved alongside the changing threat landscape, expanding into intrusion prevention, cloud visibility, and email security. At subsequent institutions, including Washington College, Darktrace was one of my first strategic investments.

Revealing the hidden threat other tools missed

One of the most surprising investigations of my career involved a data leak. Leadership suspected sensitive information from high-level meetings was being exposed, but our traditional tools couldn’t provide any answers.

Using Darktrace’s deep network visibility, down to packet-level data, we traced unusual connections to our CCTV camera system, which had been configured with a manufacturer’s default password. A small group of employees had hacked into the CCTV cameras, accessed audio-enabled recordings from boardroom meetings, and stored copies locally.

No other tool in our environment could have surfaced those connections the way Darktrace did. It was a clear example of why using AI to deeply understand how your organization, systems, and tools normally behave, matters: threats and risks don’t always look the way we expect.

Elevating a D-rating into a A-level security program

When I arrived at my last CISO role, the institution had recently experienced a significant ransomware attack. Attackers located  data  which informed their setting  ransom demands to an amount they knew would likely result in payment. It was a sobering example of how calculated and strategic modern cybercriminals have become.

Third-party cyber ratings reflected that reality, with a  D rating.

To raise the bar, we implemented a comprehensive security program and integrated layered defenses; -deploying state of the art tools and methods-  across the environment, with Darktrace at its core.

After a 90-day learning period to establish our behavioral baseline, we transitioned the platform into fully autonomous mode. In a single 30-day span, Darktrace conducted more than 2,500 investigations and autonomously resolved 92% of all false positives.

For a small team, that’s transformative. Instead of drowning in alerts, my staff focused on less than  200 meaningful cases that warranted human review.

Today, we maintain a perfect A rating from third-party assessors and have remained cybersafe.

Peace of mind isn’t about complacency

The effect of Darktrace as a force multiplier has a real human impact.

With the time reclaimed through automation, we expanded community education programs and implemented simulated phishing exercises. Through sustained training and awareness efforts, we reduced social engineering susceptibility from nearly 45% to under 5%.

On a personal level, Darktrace allows me to sleep better at night and take time off knowing we have intelligent systems monitoring and responding around the clock. For any CIO or CISO carrying institutional risk on their shoulders, that matters.

The next era: AI vs. AI

A new chapter in cybersecurity is unfolding as adversaries leverage AI to enhance scale, speed, and believability. Phishing campaigns are more personalized, impersonation attempts are more precise, and deepfake video technology, including live video, is disturbingly authentic. At the same time, organizations are rapidly adopting AI across their own environments —from GenAI assistants to embedded tools to autonomous agents. These systems don’t operate within fixed rules. They act across email, cloud, SaaS, and identity systems, often with broad permissions, and their behavior can evolve over time in ways that are difficult to predict or control.

That creates a new kind of security challenge. It’s not just about defending against AI-powered threats but understanding and governing how AI behaves within your environment, including what it can access, how it acts, and where risk begins to emerge.

From my perspective, this is a natural next step for Darktrace.

Darktrace brings a level of maturity and behavioral understanding uniquely suited to the complexity of AI environments. Self-Learning AI learns the normal patterns of each business to interpret context, uncover subtle intent, and detect meaningful deviations without relying on predefined rules or signatures. Extending into securing AI by bringing real-time visibility and control to GenAI assistants, AI agents, development environments and Shadow AI, feels like the logical evolution of what Darktrace already does so well.

Just as importantly, Darktrace is already built for dynamic, cross-domain environments where risk doesn’t sit in a single tool or control plane. In higher education, activity already spans multiple systems and, with AI, that interconnection only accelerates.

Having deployed Darktrace multiple times, I have confidence it’s uniquely positioned to lead in this space and help organizations adopt AI with greater visibility and control.

The Next Step After Mythos: Defending in a World Where Compromise is Expected

mythos cybersecurityDefault blog imageDefault blog image

Is Anthropic’s Mythos a turning point for cybersecurity?

Anthropic’s recent announcements around their Mythos model, alongside the launch of Project Glasswing, have generated significant interest across the cybersecurity industry.

The closed-source nature of the Mythos model has understandably attracted a degree of skepticism around some of the claims being made. Additionally, Project Glasswing was initially positioned as a way for software vendors to accelerate the proactive discovery of vulnerabilities in their own code; however, much of the attention has focused on the potential for AI to identify exploitable vulnerabilities for those with malicious intent.

Putting questions around the veracity of those claims to one side – which, for what it’s worth, do appear to be at least partially endorsed by independent bodies such as the UK’s AI Security Institute – this should not be viewed as a critical turning point for the industry. Rather, it reflects the natural direction of travel.

How Mythos affects cybersecurity teams  

At Darktrace, extolling the virtues of AI within cybersecurity is understandably close to our hearts. However, taking a step back from the hype, we’d like to consider what developments like this mean for security teams.

Whether it’s Mythos or another model yet to be released, it’s worth remembering that there is no fundamental difference between an AI discovered vulnerability and one discovered by a human. The change is in the pace of discovery and, some may argue, the lower the barrier to entry.

In the hands of a software developer, this is unquestionably positive. Faster discovery enables earlier remediation and more proactive security. But in the hands of an attacker, the same capability will likely lead to a greater number of exploitable vulnerabilities being used in the wild and, critically, vulnerabilities that are not yet known to either the vendor or the end user.

That said, attackers have always been able to find exploitable vulnerabilities and use them undetected for extended periods of time. The use of AI does not fundamentally change this reality, but it does make the process faster and, unfortunately, more likely to occur at scale.

While tools such as Darktrace / Attack Surface Management and / Proactive Exposure Management  can help security teams prioritize where to patch, the emergence of AI-driven vulnerability discovery reinforces an important point: patching alone is not a sufficient control against modern cyber-attacks.

Rethinking defense for a world where compromise is expected

Rather than assuming vulnerabilities can simply be patched away, defenders are better served by working from the assumption that their software is already vulnerable - and always will be -and build their security strategy accordingly.

Under that assumption, defenders should expect initial access, particularly across internet exposed assets, to become easier for attackers. What matters then is how quickly that foothold is detected, contained, and prevented from expanding.

For defenders, this places renewed emphasis on a few core capabilities:

  • Secure-by-design architectures and blast radius reduction, particularly around identity, MFA, segmentation, and Zero Trust principles
  • Early, scalable detection and containment, favoring behavioral and context-driven signals over signatures alone
  • Operational resilience, with the expectation of more frequent early-stage incidents that must be managed without burning out teams

How Darktrace helps organizations proactively defend against cyber threats

At Darktrace, we support security teams across all three of these critical capabilities through a multi-layered AI approach. Our Self-Learning AI learns what’s normal for your organization, enabling real-time threat detection, behavioral prediction, incident investigation and autonomous response. - all while empowering your security team with visibility and control.

To learn more about Darktrace’s application of AI to cybersecurity download our White Paper here.  

Reducing blast radius through visibility and control

Secure-by-design principles depend on understanding how users, devices, and systems behave. By learning the normal patterns of identity and network activity, Darktrace helps teams identify when access is being misused or when activity begins to move beyond expected boundaries. This makes it possible to detect and contain lateral movement early, limiting how far an attacker can progress even after initial access.

Detecting and containing threats at the earliest stage  

As AI accelerates vulnerability discovery, defenders need to identify exploitation before it is formally recognized. Darktrace’s behavioral understanding approach enables detection of subtle deviations from normal activity, including those linked to previously unknown vulnerabilities.

A key example of this is our research on identifying cyber threats before public CVE disclosures, demonstrating that assessing activity against what is normal for a specific environment, rather than relying on predefined indicators of compromise, enables detection of intrusions exploiting previously unknown vulnerabilities days or even weeks before details become publicly available.

Additionally, our Autonomous Response capability provides fast, targeted containment focused on the most concerning events, while allowing normal business operations to continue. This has consistently shown that even when attackers use techniques never seen before, Darktrace’s Autonomous Response can contain threats before they have a chance to escalate.

Scaling response without increasing operational burden

As early-stage incidents become more frequent, the ability to investigate and respond efficiently becomes critical. Darktrace’s Cyber AI Analyst’s AI-driven investigation capabilities automatically correlate activity across the environment, prioritizing the most significant threats and reducing the need for manual triage. This allows security teams to respond faster and more consistently, without increasing workload or burnout.

What effective defense looks like in an AI-accelerated landscape

Developments like Mythos highlight a reality that has been building for some time: the window between exposure and exploitation is shrinking, and in many cases, it may disappear entirely. In that environment, relying on patching alone becomes increasingly reactive, leaving little room to respond once access has been established.

The more durable approach is to assume that compromise will occur and focus on controlling what happens next. That means identifying early signs of misuse, containing threats before they spread, and maintaining visibility across the environment so that isolated signals can be understood in context.

AI plays a role on both sides of this equation. While it enables attackers to move faster, it also gives defenders the ability to detect subtle changes in behavior, prioritize what matters, and respond in real time. The advantage will not come from adopting AI in isolation, but from applying it in a way that reduces the gap between detection and action.

AI may be accelerating parts of the attack lifecycle, but the fundamentals of defense, detection, and containment still apply. If anything, they matter more than ever – and AI is just as powerful a tool for defenders as it is for attackers.
