The 2014 Sony hack changed everything. Bunim/Murray, like other entertainment companies, woke up to the new threats targeting our sector – jumpstarting our journey to improve security.

Bunim/Murray is the production company behind a whole host of reality television shows and is well-known for several hit series such as The Real World (MTV), Road Rules (MTV), The Simple Life (E!), Family or Fiancé (OWN), and Starting Over (syndicated). Bunim/Murray Productions infuses its finely-tuned sense of dramatic story structure to turn the ordinary tales of real people into extraordinary television programming and filmed entertainment. When landing as the CTO at Bunim/Murray, protecting our business was – and still is – a fundamental part of the job. With strong support from the CEO and CFO, I embarked on the journey to bolster cyber defense for our organization.

Bunim/Murray has some unique challenges in security: we onboard and offboard many employees, especially in production. We have a lot of BYOD (‘Bring Your Own Device’) users. Our IT staff is lean, and we don’t want to spend a lot of time and money on security resources or services. Instead, we want to focus on improving business processes – preparing our organization to launch capabilities to remain competitive in an industry undergoing transformation.

So, in searching for security tools, we were looking for technologies with the following criteria:

  • User-friendly
  • Able to continously identify and respond to the latest threats
  • Efficient with IT resources – low on false positives and alerts
  • Cost effective

After being called by Darktrace, I invited the team over to see if it made sense for them to participate in a bake-off with other tools we were assessing. At our meeting, the team at Darktrace spoke to me about the AI and machine learning capabilities, its roots in MI5 cyber operations, how it would fit into our ecosystem, and the product roadmap. Traditionally, I’m not one to be easily impressed by words – so I asked to try it out within our own organization. Within a week, we had the technology installed and up and running in our data center.

Darktrace’s Enterprise Immune System technology immediately began to baseline the dynamic ‘pattern of life’ for our business. It was the first time we had seen all the devices on our network, and we were able to drill down into all of the activity on our environment. But, even more impressive, Darktrace’s AI instantly got to work in the background, alerting us when we needed to investigate an in-progress security event in real time. Not only were we impressed with the machine learning capabilities, we were impressed with the level of support and security expertise Darktrace provided – and continues to provide our business. I canceled the bake-off and bought the system.

As we moved forward on our journey, our highest vulnerability became phishing. We subscribed to a company to train our workforce and got excellent results. We then turned on Microsoft Advanced ATP to help filter spam and phishing emails. And when I learned that Darktrace was pioneering a new approach to neutralize phishing attacks, I got on board early.

Using AI to tackle phishing head on

We were one of the first adopters of Antigena Email, and the first release surprised us. Within days, Antigena Email cut down phishing emails like no other tool I had ever seen before in my career. Using AI, Antigena Email learns all of our users’ activity patterns – how they interact and communicate both internally and externally. It creates a comprehensive and evolving understanding of what’s ‘normal’ for all of our users, and from there, identifies significant anomalies indicative of a vulnerability or threat. Once the threat is detected, Antigena Email contains the attack before it can cause damage.

Incredibly, once we started using Antigena Email, we no longer needed to spend time and money training our users on phishing awareness because we simply weren’t seeing phishing emails anymore – Antigena Email was blocking them before they ever reached the user.

We turned off our Microsoft ATP and instead used Darktrace’s plug-in to Office 365 and the Dropbox monitoring feature. These features turned out to be essential as we increased our remote workforce due to COVID-19.

Antigena Email in action: Neutralizing COVID-19 phishing campaigns

We have all seen the hundreds of thousands of COVID-19-related domains that have been created by cyber-attackers looking to launch novel phishing campaigns. By exploiting the emotional vulnerability of the situation, these attackers craft messages that are so convincing to users that they click on these malicious links. It is our unfortunate reality that threat-actors use these types of events to prey on the collective attention of the population.

As I’m sure countless other organizations have also experienced, Bunim/Murray has not been immune to these types of attacks. In fact, just last week, Antigena Email caught several phishing emails purporting to deliver corporate COVID-19 updates. These emails bore a spoofed Bunim/Murray domain, with the subject line ‘COVID-19 Update 7.4.2020’. Fortunately, due to Antigena Email’s granular analysis of what’s normal for our corporate email communication, it was able to detect this spoofed domain and block the emails from ever reaching any of the target users.

It’s exactly this type of situation that demonstrates the power of Antigena Email. Had these emails reached the user, we might have been in a situation where one of our well-intentioned employees clicked on the malicious link in an attempt to get accurate, up-to-date information – not recognizing that it would introduce malware into our environment. But with Antigena Email, we don’t have to worry about our end user behavior because the AI neutralizes it before it even gets to that point.

Technology that evolves as we do

What threats will be coming after COVID-19? I am not sure. But, I am confident that Darktrace’s AI will be on it. With its ability to ingest new and evolving information from its customer base, coupled with its top-notch security resources, we know that Darktrace will be able to continue to monitor, alert, and respond to new threats – even if those threats have never been seen before.

Always On, Always Defending: Inside the AI-Driven SOC

Default blog imageDefault blog image

Today’s SOC: A system under pressure

The SOC has been described as the:

  • Control center for security systems management  
  • Operations center for log analysis and alert response
  • Command center for network monitoring and investigation

But the CISO at a manufacturer of industrial power solutions says today’s SOC is far more dynamic:

“The SOC is an active player in a never-ending chess match where the pieces are always moving, the rules are constantly changing, and we’re continuously adjusting our tactical and strategic approaches to keep up.”

This has created a balancing act for cybersecurity professionals:

  • Support expanding digital estates to fuel innovation…or risk limiting business growth
  • Stop advanced cyberattacks at scale…or risk severe financial and reputational impacts

But balancing these responsibilities is increasingly difficult. Attackers are operating at machine speed and scale using sophisticated, adaptive techniques that overwhelm teams and bypass legacy defenses. At the same time, more than half of cybersecurity teams are understaffed, and 65% have unfilled cybersecurity positions (ISACA).

“The SOC is hitting its breaking point,” admits the VP of IT at a U.S.-based risk management services provider.”

“That’s the hard reality,” affirms a Chief Digital and Technology Officer at a North American financial services organization. “SOC teams are drowning in alerts, wasting time researching the most benign incidents while missing critical threats.”

Traditional tools lack the context and autonomous reasoning needed to determine which ones are truly dangerous, requiring analysts to manually review and respond. But with thousands of alerts hitting SOCs daily, the task exceeds human capacity, with recent industry research revealing that 40% to 42% of security alerts now go uninvestigated.

“Our old governance models of throwing bodies at it, that’s not going to work,” says the Group CIO of a multinational holding company. “Attackers move at machine speed, and our defenses have to operate at the same pace. Using AI for cybersecurity is the only way to do that.”

Why AI is essential

AI is about speed, scale, and context.

SOC teams are still expected to find the proverbial “needle in a haystack”, but the haystack keeps growing. As digital infrastructures expand and threat actors use AI to rapidly scale attacks and exploit vulnerabilities, success isn’t about keeping up but changing the approach.

This is where AI comes in, enabling security teams to operate at machine speed and scale by:

  • Analyzing vast amounts of data and correlating signals across domains within seconds
  • Detecting possible threats in real time and taking immediate action to mitigate risk
  • Prioritizing threats by severity and uncovering contextual details for rapid triage

The power of AI isn’t theoretical; it is transforming how today’s businesses operate.

The Chief Digital and Technology Officer at a financial services firm says within a single month of using Darktrace, the solution tracked billions of network events, autonomously investigated tens of millions of those incidents, and added the equivalent of 1,000 analyst hours of investigation. It also found threats that bypassed traditional tools, autonomously responding to contain or disrupt the threat on over 30,000 emails, including 18,000 the firm’s native email filter missed.

When Darktrace says it “takes action on a threat,” it generally means its platform can move beyond just detecting suspicious activity and automatically respond to contain or disrupt the threat—such as isolating a device, slowing or blocking suspicious network traffic, disabling risky user activity, or triggering security workflows—depending on how the system is configured.

AI isn’t about displacing humans.

AI is a powerful tool for handling large-scale data analysis, pattern detection, and repetitive tasks, but it cannot replace human critical thinking. By removing mindless work that does not require judgment, AI frees analysts to focus on what humans do best: applying reasoning, context, and sound decision-making to complex threats.

“AI is a workforce maximizer,” says the Chief Digital and Technology Officer. “It augments our team by monitoring and detecting threats at a scale beyond human capacity while providing the critical context we need to make faster, more confident decisions.

Rather than replacing people, AI is changing how security professionals work. Analysts can reclaim time previously spent on tedious, manual triage to focus on higher priorities and proactive initiatives like advanced threat hunting, strategic risk management, and security enablement and training.

“Aside from risk mitigation, our biggest ROI is in efficiency,” says the Head of Security at global business services provider. “What used to take 90% of our investigation time is now handled automatically, so we can focus on the final 10%, which requires critical thinking."

For SOC teams under pressure, the impact can be transformative, with security leaders reporting significant real-world outcomes using Darktrace Self-Learning AITM, including:

  • Phishing emails reduced by 99%
  • 1 million+ emails autonomously analyzed each month, with no email-based incidents reported
  • Potential threats autonomously neutralized in under four seconds, on average  
  • 99% of investigations conducted autonomously, surfacing only the high-priority 1% of threats for analyst review

How AI optimizes the SOC

To protect the modern enterprise, you absolutely need the right tools,” says CTO at leading European fashion brand. “Without them you’re a victim. With them, you’re a defender. AI and the machine speed detect/response it enables makes it the most critical tool.”

Replacing chaos with clarity and control  

It’s important to note that different AI solutions address different needs. Companies should clearly understand their specific use case and select the solution that best aligns with their goals, requirements, and operational needs.  

When it comes to choosing cybersecurity in a machine-speed threat landscape, time is the most valuable resource. Organizations require AI that can move from insight to action by:

  • Learning an organization’s unique behavioral patterners
  • Correlating signals across domains to detect anomalous activity
  • Prioritizing events and autonomously responding at scale to the vast majority
  • Quarantining high-impact threats until the SOC can investigate
  • Arming analysts with deep, contextual information to accelerate investigations

“Darktrace AI gives us threat detections based on facts, not guesses,” says the Group CIO. “It moves the SOC beyond alert overload to confident, informed decision-making. When Darktrace flags something, we pay attention. False positives are very rare, so we act with speed and confidence without second-guessing.”

Replacing anxiety with confidence and peace of mind

Every missed alert can have real-world consequences.

The strain of maintaining constant vigilance at scale without holistic visibility and automation is taking its toll on security professionals: 66% report increased stress, and nearly half say it’s the reason they’re leaving the field (ISACA).

The CIO at a professional sports organization says that’s not surprising: “If you don’t know what’s going on, anything could be happening. Operating with that level of uncertainty and control is incredibly stressful.”

AI gives SOCs the power to be proactive by unifying telemetry across network, email, identity, and cloud environments to provide a complete picture and a stronger foundation for action. The benefits for analysts, both personally and professionally, are significant:

  • Achieve greater work-life balance: “Knowing that Darktrace has our backs 24/7 and will take immediate action to stop threats  means we can now work normal hours and take vacations without worrying,” says the Chief Digital and Technology Officer.
  • Feel in control with deeper insights: “It not only stops and quarantines threats but also provides the deep context we need to quickly investigate and respond,” explains the Head of Security.  
  • Gain confidence the business is protected 24/7: “We can sleep at night. With Darktrace I’m confident that even with a small team we can protect the business 24/7,” adds the former retail CIO.

The modern SOC: A system of balance

Elevated to a core pillar of business strategy, the modern SOC is now considered:

  • The nerve center of cyber risk and proactive defense
  • The AI-powered command center for operational resilience
  • The strategic hub for contextual decision-making at scale

The SOC has evolved from a reactive center responsible for managing systems into a proactive, frontline defender and strategic business enabler—integral to innovation and growth.

AI is the key to balancing these responsibilities.

“We can only grow as fast as we can secure the business,” says the Head of Security. “AI gives us the speed, scale, and confidence to do both.”

Stopping Stealth Attacks with Precision: How Núclea Prevented a Breach Without Disruption

Default blog imageDefault blog image

Núclea is a Brazilian data and technology company that supports the country’s financial system by delivering digital services exclusively to banks and financial institutions. Operating in an environment where trust, availability, and data integrity are critical, the company faces a threat landscape that has evolved rapidly—particularly with the rise of AI-driven cyberattacks.

Brazil has experienced a wave of successful cyber incidents targeting financial institutions, many of them enabled by insiders or compromised credentials. The result was a noticeable shift in attacker strategy: instead of focusing on end customers, threat actors began targeting the institutions and platforms that underpin the financial ecosystem itself.

“Attacks became far more directed and contextual,” explains Guilherme, who leads incident response within Núclea’s security platform engineering team. “They weren’t noisy or obviously malicious—they were precise, patient, and designed to blend into normal operations.”

That precision was on full display in January 2026, when Núclea faced one of the most convincing phishing attacks the team had seen.

A real attack, built on trust and context

The attack began with a seemingly routine email.

It was sent from a real Brazilian government institution, using legitimate infrastructure and valid credentials that were later confirmed to have been compromised. Núclea had an established, ongoing relationship with this organization, and the email’s language, tone, and subject matter aligned perfectly with the type of communication the recipient team handled every day.

Attached to the email was a PDF document containing content that looked entirely legitimate.

The problem? A single URL embedded inside that PDF.

“The message itself was correct. The sender was real. The context was familiar. Even the document content made sense,” Guilherme explains. “There was just one small element that didn’t belong.”

That small detail was enough to initiate a full attack chain.

What the attackers were trying to do

If clicked, the URL would have downloaded a malicious payload designed to:

  • Collect information about the user and device
  • Identify where the system was located within the financial ecosystem
  • Install remote access tools to maintain control
  • Deploy an infostealer to extract sensitive data
  • Execute anti-forensic scripts to erase traces of the intrusion

In other words, it was a carefully engineered operation designed for persistence and stealth, not immediate disruption.

The attack also employed urgency—a classic social engineering technique. When the link didn’t open as expected, employees requested assistance from the security team, insisting the document was important and needed to be accessed quickly.

This is precisely the kind of scenario where traditional security tools struggle: almost everything about the interaction is legitimate.

Where Darktrace made the difference

Instead of blocking the entire message or relying on known indicators of compromise, Darktrace focused on behavioral context.

Darktrace recognized:

  • That the sending organization was normally trusted
  • That the communication pattern matched historical behavior
  • That the PDF content itself was not suspicious

But it also identified that the URL embedded within the document deviated from established behavioral patterns.

Rather than disrupting business operations, Darktrace took precise action: it rewrote the URL, preventing the malicious download while leaving the rest of the email untouched.

“When we analyzed it afterward, it became clear how dangerous the attack would have been,” says Guilherme. “But it never progressed—because Darktrace acted at exactly the right point.”

Subsequent forensic analysis confirmed the payload’s malicious intent. The attack never succeeded.

Precision over disruption

For Núclea, this incident reinforced a critical lesson: modern attacks don’t always look malicious—they hide within normal activity.

“What stands out to me is the precision,” Guilherme says. “Darktrace doesn’t rely on big, obvious signals. It’s effective in situations that fall outside the standard patterns we all know.”

Building resilience in a high trust ecosystem

For Núclea, cybersecurity is not just a defensive measure—it’s a business enabler.

Availability failures or successful breaches in the financial ecosystem can have immediate, large-scale consequences, from financial loss to reputational damage. Preventing those outcomes protects not just Núclea, but its partners and customers as well.

“Cyber resilience means keeping the business running—even under attack,” Guilherme explains. “And that requires people, processes, and technology working together.”

As AI continues to accelerate both attacks and defenses, the role of security is evolving. Precision, behavioral understanding, and intelligent automation are no longer optional—they’re essential.

“The easy days were yesterday,” Guilherme says. “The challenges ahead are bigger. We need to be prepared—internally and with partners that help us build resilience.”
