The modern security team faces challenges on all fronts – it is too often overstretched dealing with an increased attack surface, enabling workforces for secure remote work, and managing multiple security tools to protect that workforce. Added to that, the surge in more sophisticated phishing campaigns – now supported by AI tools – means that it’s harder than ever to pre-empt attacks. 

The needs of the security team should be a key consideration when deploying an email security solution, as it’s them who will be accountable for the success and maintenance of the product. Minimizing time spent inside the user interface – through trusted detection and response technology combined with intuitive reporting and optimized workflows – should be front of mind for vendors in order to assure teams of their value.

Taking security teams off the frontline 

No team should be spending all of their time maintaining email security policies, releasing emails that shouldn’t have been held, or holding back emails that should have been – all the things that traditional email security solutions have almost forced them to become accustomed to. A day in the life of an admin shouldn’t include tens – and certainly not hundreds – of minutes spent in their email security dashboard. 

At the moment, teams are logging in far too often, and when they do, they’re forced to make individual decisions about safe listing and blocking domains, or releasing emails. These can lead to the creation of blanket rules that open up future windows for attackers – unintended consequences that ultimately create more work in the future. This type of hand-to-hand combat puts security teams on the frontline, when their time could be much better spent doing the high-level strategic work humans are best at.  

Understanding You: A Different Approach to Email Security

In today’s discussions about email security, there is a consensus that relying on a gateway is no longer feasible. The new era is one of ICES (Integrated cloud email security) solutions and other tools leveraging artificial intelligence and APIs. But there's no point adopting new technology with an old philosophy – and most of these solutions use AI to automate the same old approach: looking at past attacks to try and stop the next. 

This is where Darktrace/Email takes a fundamentally different and unique approach. It’s not just about using AI; it’s about using it in the right capacity. Our AI understands you – learning where users log in from, who they email, their behavior throughout the day – to tailor the detection and response process according to their individual profile. There’s no point withholding an email if only a tiny element of it poses a risk – Darktrace/Email takes the least aggressive action required to neutralize a threat. Instead of a blanket allow-deny criteria, it can rewrite links or withhold attachments based on its knowledge of the user’s normal inbox activity. Stopping malicious emails while allowing legitimate emails through – with risky elements neutralized – lifts security teams out of the fire-fighting activities described earlier and frees up their time for more strategic and valuable decision-making.

Account Takeover 

Embedded account takeover protection is an essential component of modern email security. Security teams need visibility not just over email breaches but of what happens once an attacker has control of an inbox, particularly in the most damaging use cases like Business Email Compromise (BEC) and ransomware. This entails understanding a user’s behavior in their inbox, outbound emails and beyond into their wider account activity. Darktrace captures a user’s activity across email and their Microsoft or Google account in a single pane of glass – detecting and countering all of the markers that could signify a compromised account.  

Insights from other cloud applications and network devices gleaned from Darktrace's wider visibility of the business can bring a 360° understanding of the user, further enhancing detection of account takeover and other harmful activity.

What ‘user-friendly’ actually looks like 

The best user interface is one that you never have to log into. In an ideal world, teams are able to visit their tools less frequently because intelligent AI is automating work previously done by humans. This is made possible by Darktrace’s precision detection and response technology, which takes appropriate action on emails and accounts to neutralize threats without disrupting day-to-day business operations. 

The second-best user interface is one where you can quickly log in and get key insights fast, whether that’s regarding an action taken or the current activity of a user – and then get out. Darktrace/Email enables teams to get key information quickly, at both a high and granular level.  The dashboard offers immediate insights into users and emails, with a real-time snapshot of active user identities, targeted user and actioned emails, segmented by type of attack. 

At every touchpoint, Darktrace reduces friction with optimized workflows. From being able to quickly identify VIPs to safely previewing links and attachments, security teams can get the information they need without needing to switch between windows or navigate inaccessible interfaces. Explainable AI gives users natural-language summaries of individual emails or the overall health of an email environment, and simplified action flows allow security teams to personalize security for different employees – for example, sending VIPs a unique notification, or taking extra precautions around employees who work in accounting. Taken together, this meaning that admins can spend even less time managing policies.

The ideal interface is also the one that’s the most accessible to you. The mobile app guarantees convenience for security teams, making available all the main functions of the interface for on-the-go analysis at any time or place. Teams can travel or leave the office while retaining the peace of mind that if a critical incident was to occur, they would be able to get instant visibility on the data and take action without needing to get back to their desks.

With every passing day, the security team can rest easier. Every activity is taken into account to help the AI tune and adapt over time to become even better at detecting and responding to threats.   

Having email on the app is going to be game changing”

Getting the full picture

Most often, email is the entry point from which a threat actor moves stealthily throughout an organization collecting information and assets. Most solutions look at email in isolation, without prioritizing or connecting disparate events into a wider pattern. 

In contrast, Darktrace/Email integrates seamlessly with Darktrace's Cyber AI Analyst, a technology that conducts autonomous enterprise-wide investigations around every alert produced by the wider Darktrace platform. Through this integration, malicious email activity is analyzed and displayed in the context of the full security incident to which it belongs. As a result, security teams can see why and how a wider problem might have originated in email and spread to other apps, endpoints, or the wider corporate network.

Empowering employees to take an active role in security

The role of the security team can be made more difficult if employees take a lax or disengaged approach to security – or if a user is given too much control, and has the ability to make potentially dangerous decisions. Training employees on security procedures is another to-do which can easily fall to the bottom of the agenda during busy periods, especially as point-in-time phishing simulations have proven to be not particularly effective. 

To this end, Darktrace/Email uses Explainable AI to say in natural language what it thought about an email, and delivers its findings not just to the security team, but optionally to the wider workforce as well. Delivered in the form of contextual banners in emails, periodic digests, or directly in Outlook, these insights transform security education from a quarterly or yearly exercise into real-time security awareness. Our next blog will dive deeper into how employee engagement can support the security team’s efforts and harden defenses throughout the organization. 

Because Darktrace is built on a fundamentally different approach, it not only stops novel and targeted sophisticated attacks but allows legitimate emails to flow through. This is what makes it a truly set-and-forget technology, with the AI taking on much of the heavy lifting previously undertaken by security teams.

It’s Time to Rethink Cloud Investigations

cloud investigationsDefault blog imageDefault blog image

Cloud Breaches Are Surging

Cloud adoption has revolutionized how businesses operate, offering speed, scalability, and flexibility. But for security teams, this transformation has introduced a new set of challenges, especially when it comes to incident response (IR) and forensic investigations.

Cloud-related breaches are skyrocketing – 82% of breaches now involve cloud-stored data (IBM Cost of a Data Breach, 2023). Yet incidents often go unnoticed for days: according to a 2025 report by Cybersecurity Insiders, of the 65% of organizations experienced a cloud-related incident in the past year, only 9% detected it within the first hour, and 62% took more than 24 hours to remediate it (Cybersecurity Insiders, Cloud Security Report 2025).

Despite the shift to cloud, many investigation practices remain rooted in legacy on-prem approaches. According to a recent report, 65% of organizations spend approximately 3-5 days longer when investigating an incident in the cloud vs. on premises.

Cloud investigations must evolve, or risk falling behind attackers who are already exploiting the cloud’s speed and complexity.

4 Reasons Cloud Investigations Are Broken

The cloud’s dynamic nature – with its ephemeral workloads and distributed architecture – has outpaced traditional incident response methods. What worked in static, on-prem environments simply doesn’t translate.

Here’s why:

  1. Ephemeral workloads
    Containers and serverless functions can spin up and vanish in minutes. Attackers know this as well – they’re exploiting short-lived assets for “hit-and-run” attacks, leaving almost no forensic footprint. If you’re relying on scheduled scans or manual evidence collection, you’re already too late.
  2. Fragmented tooling
    Each cloud provider has its own logs, APIs, and investigation workflows. In addition, not all logs are enabled by default, cloud providers typically limit the scope of their logs (both in terms of what data they collect and how long they retain it), and some logs are only available through undocumented APIs. This creates siloed views of attacker activity, making it difficult to piece together a coherent timeline. Now layer in SaaS apps, Kubernetes clusters, and shadow IT — suddenly you’re stitching together 20+ tools just to find out what happened. Analysts call it the ‘swivel-chair Olympics,’ and it’s burning hours they don’t have.
  3. SOC overload
    Analysts spend the bulk of their time manually gathering evidence and correlating logs rather than responding to threats. This slows down investigations and increases burnout. SOC teams are drowning in noise; they receive thousands of alerts a day, the majority of which never get touched. False positives eat hundreds of hours a month, and consequently burnout is rife.  
  4. Cost of delay
    The longer an investigation takes, the higher its cost. Breaches contained in under 200 days save an average of over $1M compared to those that linger (IBM Cost of a Data Breach 2025).

These challenges create a dangerous gap for threat actors to exploit. By the time evidence is collected, attackers may have already accessed or exfiltrated data, or entrenched themselves deeper into your environment.

What’s Needed: A New Approach to Cloud Investigations

It’s time to ditch the manual, reactive grind and embrace investigations that are automated, proactive, and built for the world you actually defend. Here’s what the next generation of cloud forensics must deliver:

  • Automated evidence acquisition
    Capture forensic-level data the moment a threat is detected and before assets disappear.
  • Unified multi-cloud visibility
    Stitch together logs, timelines, and context across AWS, Azure, GCP, and hybrid environments into a single unified view of the investigation.
  • Accelerated investigation workflows
    Reduce time-to-insight from hours or days to minutes with automated analysis of forensic data, enabling faster containment and recovery.
  • Empowered SOC teams
    Fully contextualised data and collaboration workflows between teams in the SOC ensure seamless handover, freeing up analysts from manual collection tasks so they can focus on what matters: analysis and response.

Attackers are already leveraging the cloud’s agility. Defenders must do the same — adopting solutions that match the speed and scale of modern infrastructure.

Cloud Changed Everything. It’s Time to Change Investigations.  

The cloud fundamentally reshaped how businesses operate. It’s time for security teams to rethink how they investigate threats.

Forensics can no longer be slow, manual, and reactive. It must be instant, automated, and cloud-first — designed to meet the demands of ephemeral infrastructure and multi-cloud complexity.

The future of incident response isn’t just faster. It’s smarter, more scalable, and built for the environments we defend today, not those of ten years ago.

Understanding the Canadian Critical Cyber Systems Protection Act

Canadian critical cyber systems protection actDefault blog imageDefault blog image

Introduction: The Canadian Critical Cyber Systems Protection Act

On 18 June 2025, the Canadian federal Government introduced Bill C-8 which, if adopted following completion of the legislative process, will enact the Critical Cyber Systems Protection Act (CCSPA) and give Canada its first federal, cross-sector and legally binding cybersecurity regime for designated critical infrastructure providers. As of August 2025, the Bill has completed first reading and stands at second reading in the Canadian House of Commons.

Political context

The measure revives most of the stalled 2022 Bill C-26 “An Act Respecting Cyber Security” which “died on Paper” when Parliament was prorogued in January 2025, in the wake of former Prime Minister Justin Trudeau’s resignation.

The new government, led by Mark Carney since March 2025, has re-tabled the package with the same two-part structure: (1) amendments to the Telecommunications Act that enable security directions to telecoms; and (2) a new CCSPA setting out mandatory cybersecurity duties for designated operators. This blog focuses on the latter.

If enacted, Canada will join fellow Five Eyes partners such as the United Kingdom and Australia, which already impose statutory cyber-security duties on operators of critical national infrastructure.

The case for new cybersecurity legislation in Canada

The Canadian cyber threat landscape has expanded. The country's national cyber authority, the Canadian Centre for Cybersecurity (Cyber Centre), recently assessed that the number of cyber incidents has “sharply increased” in the last two years, as has the severity of those incidents, with essential services providers among the targets. Likewise, in its 2025-2026 National Cyber Threat Assessment, the Cyber Centre warned that AI technologies are “amplifying cyberspace threats” by lowering barriers to entry, improving the speed and sophistication of social-engineering attacks and enabling more precise operations.

This context mirrors what we are seeing globally: adversaries, including state actors, are taking advantage of the availability and sophistication of AI tools, which they have leverage to amplify the effectiveness of their operations. In this increasingly complex landscape, regulation must keep pace and evolve in step with the risk.

What the Canadian Critical Cyber Systems Protection Act aims to achieve

  • If enacted, the CCSPA will apply to operators in federally regulated critical infrastructure sectors which are vital to national security and public safety, as further defined in “Scope” below (the “Regulated Entities”), to adopt and comply with a minimum standard of cybersecurity duties (further described below)  which align with those its Five Eyes counterparts are already adhering to.

Who does the CCSPA apply to

The CCSPA would apply to designated operators that deliver services or systems within federal jurisdiction in the following priority areas:

  • telecommunications services
  • interprovincial or international pipeline and power line systems, nuclear energy systems, transportation systems
  • banking and clearing  
  • settlement systems

The CCSPA would also grant the Governor in Council (Federal Cabinet) with powers to add or remove entities in scope via regulation.

Scope of the CCSPA

The CCSPA introduces two key instruments:

First, it strengthens cyber threat information sharing between responsible ministers, sector regulators, and the Communications Security Establishment (through the Cyber Centre).

Second, it empowers the Governor in Council (GIC) to issue Cyber Security Directions (CSDs) - binding orders requiring a designated operator to implement specified measures to protect a critical cyber system within defined timeframes.

CSDs may be tailored to an individual operator or applied to a class of operators and can address technology, process, or supplier risks. To safeguard security and commercial confidentiality, the CCSPA restricts disclosure of the existence or content of a CSD except as necessary to carry it out.

Locating decision-making with the GIC ensures that CSDs are made with a cross-government view that weighs national security, economic priorities and international agreement.

New obligations for designated providers

The CCSPA would impose key cybersecurity compliance and obligations on designated providers. As it stands, this includes:

  1. Establishing and maintaining cybersecurity programs: these will need to be comprehensive, proportionate and developed proactively. Once implemented, they will need to be continuously reviewed
  2. Mitigating supply chain risks: Regulated Entities will be required to assess their third-party products and services by conducting a supply chain analysis, and take active steps to mitigate any identified risks
  3. Reporting incidents:  Regulated Entities will need to be more transparent with their reporting, by making the Communications Security Establishment (CSE) aware of any incident which has, or could potentially have, an impact on a critical system. The reports must be made within specific timelines, but in any event within no more than 72 hours;
  4. Compliance with cybersecurity directions:  the government will, under the CCSPA, have the authority to issue cybersecurity directives in an effort to remain responsive to emerging threats, which Regulated Entities will be required to follow once issued
  5. Record keeping: this shouldn’t be a surprise to many of those Regulated Entities which fall in scope, which are already likely to be subject to record keeping requirements. Regulated Entities should expect to be maintaining records and conducting audits of their systems and processes against the requirements of the CCSPA

It should be noted, however, that this may be subject to change, so Regulated Entities should keep an eye on the progress of the Bill as it makes its way through parliament.

Enforcement of the Act would be carried out by sector-specific regulators identified in the Act such as the Office of the Superintendent of Financial Institutions, Minister of Transport, Canada Energy Regulator, Canadian Nuclear Safety Commission and the Ministry of Industry.

What are the penalties for CCSPA non-compliance?

When assessing the penalties associated with non-compliance with the requirements of the CCSPA, it is clear that such non-compliance will be taken seriously, and the severity of the penalties follows the trend of those applied by the European Union to key pieces of EU legislation. The “administrative monetary penalties” (AMPs) set by regulation could see fines being applied of up to C$1 million for individuals and up to C$15 million for organizations.
