Major Tech Headquarters Shifts to Santa Clara
- Illumio signed a 120,000-square-foot lease at Campus at Scott in Santa Clara, shifting its headquarters from Sunnyvale in one of Silicon Valley’s bigger office bets. - The new HQ takes more than a quarter of the 460,000-square-foot campus Ellis Partners bought in 2025, with a full renovation now underway. - After years of office pullbacks, a major cybersecurity tenant taking fresh space signals real demand — not just renewals.
Office leasing is the story here — and not in the boring, back-office sense. A cybersecurity company just made a big Silicon Valley headquarters move, and that matters because Bay Area office demand has mostly been a story of downsizing, renewals, and hesitation. Illumio signed for 120,000 square feet at Campus at Scott in Santa Clara, leaving its longtime Sunnyvale headquarters for a much larger new base. That turns a local real-estate item into something bigger — a signal that at least some tech companies are willing to make long-term bets on physical offices again. ### Why is this a real move? Illumio isn’t just opening a satellite office. The company is moving its headquarters from 920 De Guigne Drive in Sunnyvale to Santa Clara, and the new lease is large enough to count as a real footprint decision, not a branding tweak. Illumio’s current Sunnyvale site is listed as its headquarters today, which makes the shift concrete. (news.theregistrysf.com) ### Why does 120,000 square feet matter? Because that is a big chunk of a single campus. Campus at Scott totals about 460,000 square feet across three buildings, so Illumio is taking more than one-quarter of the whole complex. In a market where landlords have spent the past few years chopping up space, offering concessions, and waiting out vacancies, one tenant taking that much room changes the math fast.

Ellis Partners bought it in September 2025 with Baupost, and the owners have been planning a broad amenity and renovation push. That matters because Illumio is not moving into a tired leftover building — it’s moving into a campus the new owners are actively repositioning for a post-slump market. (news.theregistrysf.com) ### Why Santa Clara instead of Sunnyvale? Basically, Santa Clara has become one of the clearer office-recovery pockets in Silicon Valley. Big employers are already concentrated there, the city has newer campus inventory, and landlords have been willing to spend to make space competitive. For a company like Illumio, which sells enterprise cybersecurity and still hosts in-person events at its current HQ, the move looks less like retreat and more like a reset into newer space that can support recruiting, meetings, and customer-facing work. (ellispartners.com) That last part is an inference, but it fits the size of the lease and Illumio’s ongoing use of its Sunnyvale office for events. ### Does this mean office is “back”? Not broadly. The catch is that one large lease does not erase the Bay Area’s vacancy problem. But this kind of deal matters because it is fresh demand, not just a tenant renewing in place. That distinction is huge. Renewals keep a building from getting worse. A headquarters relocation into a newly repositioned campus suggests some companies now see enough stability to move, build out, and commit. (illumio.com) ### What does Sunnyvale lose? Mostly prestige and daytime activity. Headquarters moves can shift where employees commute, where customers visit, and where nearby restaurants and service businesses get lunch traffic. Illumio’s old office is much smaller than the new one, so Sunnyvale is not just losing an address line — it is losing a tenant whose next chapter will happen elsewhere. ### Why does this fit Illumio specifically? (news.theregistrysf.com) Cybersecurity has held up better than a lot of software categories, and Illumio is still a sizable private company with a national customer base. A company in that position can use a headquarters move to signal confidence internally and externally — to employees, customers, investors, and recruits. You do not take 120,000 square feet in 2026 unless you think the office still matters to how your business runs. (craft.co) ### Bottom line? This is one lease, not a market-wide comeback. But it is exactly the kind of lease people have been waiting for — a named tech company, a big block of space, a headquarters move, and a landlord willing to renovate around it. In Silicon Valley office real estate, that counts as a real shift. (news.theregistrysf.com)
