Ostra Security has closed a .5M Series A extension to enhance its managed cybersecurity services for SMBs, strengthen partner programs, and accelerate growth.
MINNEAPOLIS, MN – August 7, 2025 – Ostra Security, a managed cybersecurity leader, has closed a Series A extension round, bringing the total funding for this round to $7.5 million. The investment reinforces Ostra’s mission to deliver Fortune-100 caliber cybersecurity solutions purpose-built for small and mid-sized businesses (SMBs)—a segment increasingly targeted by cybercriminals.
SMBs account for the majority of cyberattack victims but often lack the resources to deploy sophisticated defenses. Ostra bridges this gap with a fully managed, multi-layered Security-as-a-Service model, combining enterprise-grade technology with expert human support.
This new funding will enable Ostra to scale these solutions, making robust cyber protection more accessible to organizations that need it most.
Ostra will channel the Series A extension toward:
Expanding customer-facing teams in account management and customer success
Strengthening channel partner programs, recruiting and supporting trusted MSPs and advisors
Accelerating its go-to-market strategy through a channel-first model
Cyberattacks are rising, and SMBs are disproportionately at risk due to fragmented IT setups and limited budgets. Ostra’s approach flips the script—offering enterprise-grade defenses tailored for smaller businesses at a fraction of the traditional cost.
The Series A extension represents more than capital—it’s a strategic investment in closing the cybersecurity gap for SMBs worldwide.
“We believe every business, regardless of size, deserves access to world-class security,” said an Ostra Security spokesperson. “This funding allows us to empower SMBs with the same caliber of protection that Fortune 100 companies rely on.”
