Built to Last: The Career Journey of Arnie Lopez, SVL Advisory Board Member

by Sergio Domeyko June 22, 2026

From repairing computers at Mervyn’s to leading systems engineering at a frontier AI cybersecurity company. Arnie Lopez’s journey is not a shortcut story. It is a testament to what happens when talent meets tenacity, and when community shows up.

There is a version of the American Dream that gets told in highlight reels. One big break. One viral moment. One door that swings wide open. That is not Arnie Lopez’s story. His story is better.

It is a story built one decade at a time. One certification at a time. One person mentored at a time. Thirty years of showing up, mastering the craft, and going back to hold the door open for the next person behind him. And now, as VP of Systems Engineering at Forescout, a company at the forefront of AI-driven cybersecurity, Arnie Lopez stands as proof that the long game is always worth playing.

He is also proof that community matters. Not as a sentiment. As infrastructure.

From La Paz to the Bay Area: The Foundation 

Arnie Lopez was born in La Paz, Bolivia and came to San Francisco, California with his family as a young child. The Bay Area became home, and the work ethic and values he carried from his upbringing never left him.

He attended high school in Union City, California, then enrolled at San Francisco State University on a partial scholarship, working two part-time jobs to pay his way through. He earned a degree in International Business, a credential that reflected both his ambition and his awareness that the world was bigger than any single industry.

What drove him then, and still drives him today, is something he describes simply: an unrelenting curiosity and a genuine desire to keep learning. Those two qualities would carry him further than any single degree or certification ever could.

 

The Grind: Building a Career from the Ground Up

Arnie’s career did not begin with a title. It began with a repair bench.

His first role was at Mervyn’s and PeopleSoft, where he started as an engineer and quickly distinguished himself. He taught himself to build application servers, then mastered IBM Mainframe Security Administration entirely through self-directed study. That pattern of deliberate self-investment would define everything that followed.

At PeopleSoft, he became a Network Security Engineer, responsible for developing and securing corporate applications and networks. That work led to an offer from Cisco, one of Silicon Valley’s most influential names, where he joined as a Systems Engineer specializing in Security. He was named SE of the Year, then SE Manager of the Year. Along the way he earned his CCIE, CISSP, and AWS Cloud Practitioner certification.

At Cisco, something deeper shifted. Arnie discovered that his greatest strength was not only building systems, but developing people. He stepped into leadership and never looked back.

What followed was a career spanning the most consequential names in enterprise technology: Cisco. Proofpoint. Informatica. McAfee. Skyhigh Security. New Relic. And now, Forescout.

Thirty years. Multiple industries. Constant reinvention. Zero shortcuts.

But the transition into leadership was not without its challenges. When asked about the hardest moment in his career, Arnie did not point to a layoff or a market downturn. He pointed inward:

“The hardest moment wasn’t a single event. It was a transition. I spent the first decade of my career going deep technically. Then I moved into a leadership role, and suddenly I wasn’t the expert in the room anymore. I had to learn to lead people who were better at technical work than I was. That’s a humbling shift, and not everyone makes it cleanly. What kept me going was realizing that my job wasn’t to be the smartest person in the room. It was to build the room.” — Arnie Lopez

Once he internalized that, everything changed. And every company that followed deepened that belief. The work, he says, is always about the people. 

 

The Leader: Opening Doors He Once Had to Push Through

Somewhere along the way, Arnie Lopez made a decision that separates truly great leaders from merely successful ones. He decided that reaching the top was not the finish line. It was the starting point for something larger.

Throughout his career, Arnie has been a dedicated mentor to young technology professionals, with a particular investment in Latinos entering the field. He knows what it means to walk into rooms where few people share your background. He has spent decades making sure fewer people have to navigate that experience alone.

One story stays with him:

“I think about a young engineer I worked with early in my time leading SE teams. Sharp technically, but he didn’t see a path for himself into leadership, partly because he hadn’t seen many people who looked like him in those roles. I pushed him toward his first customer-facing opportunity. He resisted. I pushed harder. A few years later, he called me to say he was stepping into his first SE manager role. What he said stuck with me: ‘I didn’t think this was the kind of career I could have until you acted like it was already decided.’”

He pauses on that line. Because that is the whole point.

“Sometimes the most powerful thing you can do for someone is just refuse to accept their self-imposed ceiling.” — Arnie Lopez, SVL Advisory Board Member

Beyond the office, Arnie and his family volunteer regularly at the Alameda County and 2nd Harvest Food Banks in the Bay Area, a reflection of values that were shaped long before Silicon Valley entered the picture.

 

The SVL Chapter: When Community Becomes a Career Asset

When Silicon Valley Latino first featured Arnie Lopez as a Cultura Ambassador and Advisory Board Member, the goal was straightforward: tell the story of a leader whose journey deserved to be known and whose presence strengthened the community. What followed demonstrated something SVL believes deeply: visibility is not vanity. It is strategy.

The attention found him. Executives noticed. Recruiters took note. And when the opportunity at Forescout emerged, Arnie was already on the radar of the people who needed to know his name.

He also sat down with SVL Founder Alex for an in-depth interview on AI security, bringing 30 years of expertise directly to SVL’s audience, breaking down how everyday people and the Latino community can protect themselves in an AI-driven world. The conversation was published on SVL and widely shared, cementing Arnie’s role not just as someone this community supports, but as someone who actively builds it.

After accepting the role at Forescout, he reached out to SVL directly:

“SVL gave me something Silicon Valley doesn’t always hand you voluntarily: a community of people who understand the full picture of who I am. I grew up bilingual, first-generation in a lot of the rooms I walked into, and there’s a tax that comes with that. You’re managing the work and managing the code-switching simultaneously. SVL was the first place where I didn’t have to pay that tax. Professionally, it opened real doors, including introductions to executives, visibility with recruiters, peer relationships I still draw on today. What it did for me personally was more fundamental: it reminded me that I belong in these rooms, and that I have a responsibility to bring others with me.”

That is not a testimonial. That is evidence. When a community invests in lifting its own, through storytelling, visibility, and sustained relationships, the returns are real. Measured not in inspiration alone, but in careers advanced and doors opened.

“SVL was the first place where I didn’t have to pay that tax.” — Arnie Lopez

 

The Next Chapter: VP of Systems Engineering at Forescout

Effective this May, Arnie Lopez stepped into his newest role as Vice President of Systems Engineering at Forescout, a global cybersecurity leader helping organizations prepare for the new world of Frontier AI security threats.

Forescout’s mission is straightforward: most organizations do not actually know everything that is connected to their network. Managed laptops, yes, but factory equipment, smart sensors, operational technology, and unmanaged devices? Not so much. That visibility gap is where attackers live. Forescout sees every device, even those without traditional security software installed, and takes action, automatically enforcing policy, isolating threats, and giving security teams the situational awareness they need to move fast.

In Arnie’s own words:

“Right now, with AI changing the threat landscape in real time, that foundation has never mattered more. I’ve spent my career in networking and security. Forescout is where all of that converges, a perfect place for me to call home.”

What solidified his decision was not just the technology. It was the culture.

“At this point in my career, I want to put my 30 years of experience to work with people I like on a problem that is real, urgent, and impacts everyday lives. That is exactly what I have found at Forescout.”

Forescout Chief Revenue Officer Rob Amezcua welcomed Arnie’s arrival:

“True innovation happens when different perspectives come together to solve urgent, real-world problems. In a field as fast-moving as cybersecurity, Arnie brings the fresh perspective required to solve our customers’ most complex network challenges while embodying the collaborative culture we are building at Forescout. We are incredibly proud to have his vision guiding our teams and driving our mission forward.” — Rob Amezcua, Chief Revenue Officer, Forescout

 

A Message to the Next Generation

For every young Latino professional reading this who is early in their career and quietly wondering whether they belong, Arnie has a message. And he delivers it without softening the edges:

“You belong here. Not someday. Right now. I started as an engineer, bilingual, from the Bay Area, with a degree in International Business from San Francisco State. Not the typical profile. I spent many great years there, became SE of the Year, SE Manager of the Year, earned a CCIE, CISSP, and AWS certifications. Then I went on to lead global presales organizations at Cisco, Proofpoint, McAfee, New Relic, and now VP at Forescout. None of that happened because the industry handed it to me. It happened because I refused to let anyone else define what was possible for me, and because people along the way held the door open.” — Arnie Lopez

He closes with the line that defines his entire philosophy:

“Your accent, your name, your background. Those aren’t liabilities. They’re the thing that makes you see problems differently. That’s an edge. Use it.”

 

Built to Last

Thirty years. Bolivia to the Bay Area. Repair bench to the executive suite. And through it all, the mentorship, the volunteering, the community investment, the steady consistency of a man who never forgot where he came from or why it mattered.

Arnie Lopez did not get here by chance. He got here by doing the work, staying curious, and refusing to stop growing. He also got here because he understood something that too many people overlook: individual success built in isolation is fragile. Success built in community, through lifting others, showing up, being seen and seeing others in return, is the kind that endures.

We are proud to call him a Silicon Valley Latino Advisory Board Member. We are proud to tell his story. And we are proud that community, the storytelling, the visibility, and the relationships, played even a small role in what he continues to build.

Silence is complicity. And so is invisibility. Arnie Lopez chose to be seen. He chose to show up. And he chose to bring others with him.

Arnie Lopez has been building for thirty years, and he is still adding rungs. This is what leadership with purpose looks like. — Silicon Valley Latino
