With the widespread adoption of cloud email services, security vendors are collaborating with cloud providers to offer faster and more seamless ways of rolling out security solutions like API-driven one-click deployment. These new methods of deployment can install in seconds, reduce the risk of email disruption and scale without any additional configurations.  

Third-party SEGs (Secure Email Gateways) traditionally provided the foundation for email security and operations, operating via an on-premises or virtual appliance or a cloud service. SEGs process and screen all email traffic according to a set of pre-defined rules to protect against phishing attacks. In order to implement, these solutions require organizations to reroute their mail exchange (MX) record to direct emails towards the SEG.

In recent years Microsoft and Google have leveled up their security significantly, making valuable extensions to foundational email security. However, it is just that, foundational. The current email threat landscape has led to more sophisticated malware delivery techniques and social engineering tactics, creating demand for advanced email security solutions that can collaborate with native vendors and combine diverse approaches to provide in-depth defense – for example, the established partnership between Darktrace and Microsoft. Indeed, Gartner reported that the industry is moving towards a combination of native provider security and API-based vendors, allowing for full-breadth coverage of the variety of use cases.

API-driven deployment  

With cloud email services now ubiquitous for almost every business, it makes sense for email security vendors to leverage these cloud services for deployment. Because these products co-exist with, rather than replace, the in-built security of cloud email, they don’t require rerouting the domain name services mail exchanger (DNS MX) record. Instead, vendors can offer seamless delivery of their products by using APIs, which integrate fully via cloud applications without affecting the email delivery path – making installation and uninstallation straightforward while offering uninterrupted workflows.  

And communication doesn’t stop at email; in the world of hybrid work, email is just one of the tools employees use to connect and send sensitive information. APIs allow security solutions to integrate with other collaboration tools – including Microsoft Teams, Slack, Salesforce and Dropbox – to allow for full visibility of an organization beyond just the inbox.

API + Journaling  

While APIs are unmistakably the future of deployment, they can also be easily augmented. That’s where API+Journaling comes in. Where API-only analyzes emails after they have passed through initial cloud security, and has the ability to quarantine or return them to the inbox post-delivery, API with added journaling in Microsoft 365 takes the raw email data before it enters the inbox to analyze in parallel with the provider’s native security.  

As both scenarios take place at machine speed the difference is often imperceptible, but there can be instances where API-only is marginally slower – in certain cases even a second can be detrimental when dealing with such a critical communication platform as email. For these organizations, journaling reduces latency to ensure best in class detection speeds, as much as 30 times faster than API-only.

Darktrace/Email: Flexible Deployment to Suit You  

In a crowded market for ICES vendors, those who can offer flexible deployment will remain ahead of the game. Organizations should be able to choose from speedy deployment using API-only, or longer deployment with journaling – with the option to deploy via cloud or on-premise.  

Darktrace/Email offers the best of both worlds – giving customers the choice of deployment via API or API+Journaling in Microsoft 365 to meet their organization’s needs. Equally, they can choose to deploy fully via cloud or fully on premise, whichever best suits their team setup. Either way, there’s no change to the email path. With 1-click deployment that installs in seconds, or 5-minute deployment with added journaling – it can scale from just a handful of inboxes to tens of thousands, without any re-routing or additional configurations aside from accepting permissions.

Added features increase the efficiency of workflows to benefit teams – such as the ability to recuperate a delivered message from a user’s inbox post-delivery, whether it is in bulk or a single email. Seamless integration within the email application creates an intuitive user experience, introducing non-invasive banners and simple AI analysis inside the inbox.  

Security teams can also get a clearer picture of how effective their current email solution is, as emails aren’t stopped by the SEG before reaching the provider – allowing for improved visibility from first deployment.  

Darktrace works with email providers to take advantage of their native security and combine it with our Self-Learning AI, offering flexibility without compromising on speed of deployment. This approach enhances detection by leveraging the same API connections to gather additional context from other SaaS applications like Microsoft Teams and SharePoint – hardening defenses across the organization.

What the Darktrace Annual Threat Report 2026 Means for Security Leaders

Image of the Earth from spaceDefault blog imageDefault blog image

The challenge for today’s CISOs

At the broadest level, the defining characteristic of cybersecurity in 2026 is the sheer pace of change shaping the environments we protect. Organizations are operating in ecosystems that are larger, more interconnected, and more automated than ever before – spanning cloud platforms, distributed identities, AI-driven systems, and continuous digital workflows.  

The velocity of this expansion has outstripped the slower, predictable patterns security teams once relied on. What used to be a stable backdrop is now a living, shifting landscape where technology, risk, and business operations evolve simultaneously. From this vantage point, the central challenge for security leaders isn’t reacting to individual threats, but maintaining strategic control and clarity as the entire environment accelerates around them.

Strategic takeaways from the Annual Threat Report

The Darktrace Annual Threat Report 2026 reinforces a reality every CISO feels: the center of gravity isn’t the perimeter, vulnerability management, or malware, but trust abused via identity. For example, our analysis found that nearly 70% of incidents in the Americas region begin with stolen or misused accounts, reflecting the global shift toward identity‑led intrusions.

Mass adoption of AI agents, cloud-native applications, and machine decision-making means CISOs now oversee systems that act on their own. This creates an entirely new responsibility: ensuring those systems remain safe, predictable, and aligned to business intent, even under adversarial pressure.

Attackers increasingly exploit trust boundaries, not firewalls – leveraging cloud entitlements, SaaS identity transitions, supply-chain connectivity, and automation frameworks. The rise of non-human identities intensifies this: credentials, tokens, and agent permissions now form the backbone of operational risk.

Boards are now evaluating CISOs on business continuity, operational recovery, and whether AI systems and cloud workloads can fail safely without cascading or causing catastrophic impact.

In this environment, detection accuracy, autonomous response, and blast radius minimization matter far more than traditional control coverage or policy checklists.

Every organization will face setbacks; resilience is measured by how quickly security teams can rise, respond, and resume momentum. In 2026, success will belong to those that adapt fastest.

Managing business security in the age of AI

CISO accountability in 2026 has expanded far beyond controls and tooling. Whether we asked for it or not, we now own outcomes tied to business resilience, AI trust, cloud assurance, and continuous availability. The role is less about certainty and more about recovering control in an environment that keeps accelerating.

Every major 2026 initiative – AI agents, third-party risk, cloud, or comms protection – connects to a single board-level question: Are we still in control as complexity and automation scale faster than humans?

Attackers are not just getting more sophisticated; they are becoming more automated. AI changes the economics of attack, lowering cost and increasing speed. That asymmetry is what CISOs are being measured against.

CISOs are no longer evaluated on tool coverage, but on the ability to assure outcomes – trust in AI adoption, resilience across cloud and identity, and being able to respond to unknown and unforeseen threats.

Boards are now explicitly asking whether we can defend against AI-driven threats. No one can predict every new behavior – survival depends on detecting malicious deviations from normal fast and responding autonomously.  

Agents introduce decision-making at machine speed. Governance, CI/CD scanning, posture management, red teaming, and runtime detection are no longer differentiators but the baseline.

Cloud security is no longer architectural, it is operational. Identity, control planes, and SaaS exposure now sit firmly with the CISO.

AI-speed threats already reshaping security in 2026

We’re already seeing clear examples of how quickly the threat landscape has shifted in 2026. Darktrace’s work on React2Shell exposed just how unforgiving the new tempo is: a honeypot stood up with an exposed React was hit in under two minutes. There was no recon phase, no gradual probing – just immediate, automated exploitation the moment the code appeared publicly. Exposure now equals compromise unless defenses can detect, interpret, and act at machine speed. Traditional operational rhythms simply don’t map to this reality.

We’re also facing the first wave of AI-authored malware, where LLMs generate code that mutates on demand. This removes the historic friction from the attacker side: no skill barrier, no time cost, no limit on iteration. Malware families can regenerate themselves, shift structure, and evade static controls without a human operator behind the keyboard. This forces CISOs to treat adversarial automation as a core operational risk and ensure that autonomous systems inside the business remain predictable under pressure.

The CVE-2026-1731 BeyondTrust exploitation wave reinforced the same pattern. The gap between disclosure and active, global exploitation compressed into hours. Automated scanning, automated payload deployment, coordinated exploitation campaigns, all spinning up faster than most organizations can push an emergency patch through change control. The vulnerability-to-exploit window has effectively collapsed, making runtime visibility, anomaly detection, and autonomous containment far more consequential than patching speed alone.

These cases aren’t edge scenarios; they represent the emerging norm. Complexity and automation have outpaced human-scale processes, and attackers are weaponizing that asymmetry.  

The real differentiator for CISOs in 2026 is less about knowing everything and more about knowing immediately when something shifts – and having systems that can respond at the same speed.

CVE-2026-1731: How Darktrace Sees the BeyondTrust Exploitation Wave Unfolding

Default blog imageDefault blog image

Note: Darktrace's Threat Research team is publishing now to help defenders. We will continue updating this blog as our investigations unfold.

Background

On February 6, 2026, the Identity & Access Management solution BeyondTrust announced patches for a vulnerability, CVE-2026-1731, which enables unauthenticated remote code execution using specially crafted requests.  This vulnerability affects BeyondTrust Remote Support (RS) and particular older versions of Privileged Remote Access (PRA) [1].

A Proof of Concept (PoC) exploit for this vulnerability was released publicly on February 10, and open-source intelligence (OSINT) reported exploitation attempts within 24 hours [2].

Previous intrusions against Beyond Trust technology have been cited as being affiliated with nation-state attacks, including a 2024 breach targeting the U.S. Treasury Department. This incident led to subsequent emergency directives from  the Cybersecurity and Infrastructure Security Agency (CISA) and later showed attackers had chained previously unknown vulnerabilities to achieve their goals [3].

Additionally, there appears to be infrastructure overlap with React2Shell mass exploitation previously observed by Darktrace, with command-and-control (C2) domain  avg.domaininfo[.]top seen in potential post-exploitation activity for BeyondTrust, as well as in a React2Shell exploitation case involving possible EtherRAT deployment.

Darktrace Detections

Darktrace’s Threat Research team has identified highly anomalous activity across several customers that may relate to exploitation of BeyondTrust since February 10, 2026. Observed activities include:

Outbound connections and DNS requests for endpoints associated with Out-of-Band Application Security Testing; these services are commonly abused by threat actors for exploit validation.  Associated Darktrace models include:

  • Compromise / Possible Tunnelling to Bin Services

Suspicious executable file downloads. Associated Darktrace models include:

  • Anomalous File / EXE from Rare External Location

Outbound beaconing to rare domains. Associated Darktrace models include:

  • Compromise / Agent Beacon (Medium Period)
  • Compromise / Agent Beacon (Long Period)
  • Compromise / Sustained TCP Beaconing Activity To Rare Endpoint
  • Compromise / Beacon to Young Endpoint
  • Anomalous Server Activity / Rare External from Server
  • Compromise / SSL Beaconing to Rare Destination

Unusual cryptocurrency mining activity. Associated Darktrace models include:

  • Compromise / Monero Mining
  • Compromise / High Priority Crypto Currency Mining

And model alerts for:

  • Compromise / Rare Domain Pointing to Internal IP

IT Defenders: As part of best practices, we highly recommend employing an automated containment solution in your environment. For Darktrace customers, please ensure that Autonomous Response is configured correctly. More guidance regarding this activity and suggested actions can be found in the Darktrace Customer Portal.
