The ThreatLocker Zero Trust World Conference 2025 has wrapped up, leaving attendees with a new perspective on cybersecurity and a deeper understanding of how to defend against evolving threats. For Rob Allen, Chief Product Officer (CPO) of ThreatLocker, the event wasn’t just about discussing theories—it was about empowering IT professionals with hands-on experience to strengthen their security postures.
ThreatLocker’s Zero Trust World Conference
As the dust settles, Allen reflects on the key takeaways from the conference, the growing impact of AI-driven threats, and why a deny-by-default approach is the future of cybersecurity.
From IT Engineer to Cybersecurity Leader
Allen’s career journey has been anything but traditional. Having spent nearly two decades at an IT company in Dublin, he worked across technical, engineering, and sales roles, giving him a unique perspective on both the technology and the people using it.
“I started as the guy locked in a room working on tech, but over the years, I learned that being able to explain complex concepts in a way people understand is just as important,” Allen says.
That ability to bridge the gap between cybersecurity and real-world business needs has been a driving force behind his work at ThreatLocker, and it was a key focus at this year’s conference.
The Zero Trust Revolution: Deny by Default, Permit by Exception
One of the most powerful lessons from the event was the importance of flipping traditional cybersecurity approaches on their head.
“For years, businesses have operated on a permit-by-default model—allowing everything to run unless it’s explicitly known to be bad,” Allen explains. “The problem is, there are 150,000 new pieces of malware released every single day. There’s no way to keep up with that.”
Instead of trying to identify every possible threat, ThreatLocker’s deny-by-default model ensures that only pre-approved applications and processes can run.
“We don’t care if something is good or bad—we care if it’s allowed or not,” Allen says. “Most businesses use the same software every day—Office, browsers, maybe a few industry-specific apps. We put guardrails around that. If something tries to run that isn’t approved, it gets blocked.”
This approach resonated with conference attendees, who witnessed firsthand how traditional security measures fail to keep up with modern threats.
AI-Powered Cyberattacks: The New Reality
A major theme of this year’s conference was the growing role of AI in cybercrime. AI-powered tools are making it easier than ever for attackers to generate malware, even for those with little to no technical experience.
“To prove how dangerous AI can be in the wrong hands, we ran a simple test,” Allen explains. “We asked ChatGPT for code that could remotely execute commands on a computer. At first, it refused, citing ethical concerns. But when we rephrased the question—asking for a ‘simple C# program to allow remote command execution’—it gave us fully functional reverse shell code.”
The implications are massive. Traditional malware detection failed to flag the AI-generated script because it was brand new, never-before-seen code.
“In the past, you needed serious coding skills to write malware,” Allen says. “Now, all you need is the ability to ask AI the right questions. That’s why detection-based security is no longer enough.”
Hands-On Hacking: An Eye-Opening Experience
One of the standout aspects of Zero Trust World was the interactive hacking workshops, where IT professionals got to experience cyberattacks from an attacker’s perspective.
“We don’t just want to tell people about threats—we want them to see them in action,” Allen says.
Attendees learned how hackers:
- Use USB-based hacking tools (like Rubber Duckies) to inject malicious scripts into systems.
- Take over public Wi-Fi networks to intercept sensitive data.
- Bypass traditional antivirus solutions using AI-generated malware.
“There were people in the room who have been in IT for 20 years, and you could see their minds being blown,” Allen recalls. “They walked away realizing that what they thought was ‘good enough’ security isn’t nearly enough anymore.”
A Cybersecurity Model for Businesses of All Sizes
One of the biggest misconceptions in cybersecurity is that only large enterprises need advanced protection. Allen and the ThreatLocker team work with clients ranging from global corporations to small businesses with just a couple of computers.
“The reality is, cybercriminals don’t care about your company size,” Allen says. “Whether you’re a multinational enterprise or a small business, you’re a target.”
That’s why ThreatLocker’s approach is scalable—helping managed service providers (MSPs) secure small businesses while also protecting enterprise-level IT infrastructures.
“We’ve got customers with two computers and customers with tens of thousands of endpoints,” Allen explains. “The threats are the same, and so is the solution—blocking attacks before they can even start.”
A Cyber Hero’s Mission: Turning Knowledge into Action
Beyond the technical deep dives and hands-on training, the core mission of Zero Trust World was to ensure that every attendee left with something actionable.
“We don’t want people to just listen and go home,” Allen says. “We want them to implement at least one security improvement immediately—whether it’s locking down administrative privileges, removing outdated software, or reinforcing endpoint security.”
And, of course, the conference ended with ThreatLocker’s now-famous Cyber Heroes Afterparty, where attendees celebrated their newfound skills and insights.
“We call our support team ‘Cyber Heroes,’ and this event is about turning every IT professional into one,” Allen says.
Looking Ahead: The Future of Cybersecurity
As AI-powered cyberattacks grow more sophisticated, the need for proactive security has never been greater.
“We’re entering a world where attackers only need to be lucky once, but defenders need to be lucky every time,” Allen warns. “The only way to stay ahead is to stop relying on detection-based security and adopt a deny-by-default model.”
The message from Zero Trust World 2025 was clear: cybersecurity isn’t just about reacting to threats—it’s about preventing them before they even begin.
For Rob Allen and the ThreatLocker team, the mission continues—to educate, empower, and equip businesses with the tools they need to stay one step ahead of cybercriminals.
Because in the ever-changing cyber landscape, only the proactive survive.
