Intrusion Inc. Reports Second Quarter 2025 Results

Recent Intrusion Shield expansion highlights progress toward sustainable growth and profitability

PLANO, Texas, August 12, 2025 (ACCESSWIRE) -- Intrusion Inc. (NASDAQ: INTZ) (“Intrusion” or the “Company”), a leader in cyberattack prevention solutions, announced today financial results for the second quarter ended June 30, 2025.

Recent Financial & Business Highlights:

· Received an additional $3.0 million for continued Department of Defense contract support, with funding driving operational deployment of critical infrastructure monitoring tools and deepens research-driven threat analysis capabilities.

· Achieved fifth sequential quarter of revenue improvement.

“The second quarter marked another positive step forward for Intrusion as we continued to deliver consistent sequential revenue growth and make meaningful progress toward our objective of achieving sustainable growth and long-term profitability,” said Tony Scott, CEO of Intrusion. “Revenue growth during the quarter was largely driven by the continued improvement in the scope of our suite of Shield products, particularly within critical infrastructure, which we continue to view as a highly promising market for Intrusion, given the escalating risks from ransomware, supply chain disruptions, and other threats targeting vital infrastructure assets. Our momentum in this area was recently highlighted by the extension and expansion of our contract with the Department of Defense, which is already generating incremental revenue. As we look ahead, our priorities remain focused on enhancing our product offerings, accelerating customer acquisition, and strengthening our sales pipeline to ensure Intrusion is well-positioned to capture long-term growth.”

Second Quarter Financial Results

Revenue for the second quarter of 2025 was approximately $1.9 million, representing an increase of 28% on a year-over-year basis. The sequential increase in revenue for the second quarter of 2025 was driven by new customers signed in recent quarters, including the U.S. Department of Defense award for the use of both Intrusion Shield technology and consulting services.

The gross profit margin was 76% for the second quarter of 2025, which was flat compared to the second quarter of 2024. Gross margin varies based on product mix.

Operating expenses for the second quarter of 2025 were $3.5 million, up $0.4 million compared to the second quarter of 2024.

Net loss for the second quarter of 2025 was $2.0 million, or $0.10 per share, compared to a net loss of $2.1 million for the second quarter of 2024.

As of June 30, 2025, cash and cash equivalents were $4.7 million, and short-term investments in U.S. Treasuries were $3.7 million.
