Palo Alto Networks launches Prisma AIRS to secure enterprise AI
Palo Alto Networks has unveiled Prisma AIRS, an AI security platform designed to offer protection for the entire enterprise AI ecosystem, including applications, agents, models, and data.
The platform addresses the security needs of organisations adopting AI technologies at scale, particularly as enterprises increasingly employ AI applications and large language models (LLMs) in varied functions such as customer support and code generation.
Prisma AIRS provides several key security capabilities, including AI model scanning to detect vulnerabilities, posture management to monitor permissions and data exposures, AI red teaming to simulate attacks against AI systems, runtime security to guard against evolving threats during operation, and security for AI agents, including those built with no-code or low-code tools.
AI model scanning enables organisations to assess their AI models for vulnerabilities such as tampering, malicious scripts, and deserialization attacks. This component aims to help organisations adopt AI models safely by identifying security risks before deployment.
Posture management provides insights into security risks associated with an enterprise's AI ecosystem. It highlights issues such as excessive permissions, sensitive data exposure, and both platform and access misconfigurations.
The AI red teaming feature allows organisations to perform automated penetration testing on AI applications and models by utilising a red teaming agent. This agent stress-tests AI deployments, learning and adapting like a real attacker to uncover potential exposures and lurking risks before malicious actors can exploit them.
Runtime security within Prisma AIRS protects AI applications powered by LLMs against threats encountered during operation. These threats may include prompt injection, malicious code execution, toxic content, sensitive data leaks, resource overload, and hallucination.
To address risks associated with AI agents, Prisma AIRS includes safeguards for both standard and no-code/low-code platforms. It aims to defend against agentic threats such as identity impersonation, memory manipulation, and misuse of tools.
Lee Klarich, Chief Product Officer for Palo Alto Networks, said, "AI agents and apps are transforming the way we work and live. In parallel, the attack surface isn't just expanding, it's fundamentally changing. The last thing organizations need is more point products to secure their use of AI. Organizations need best-in-class security delivered via the right architecture - platformization is that architecture. Prisma AIRS addresses both traditional and AI specific threats with best-in-class security capabilities delivered in a comprehensive, unified AI security platform that enables organizations to deploy AI bravely."
Anand Oswal, Senior Vice President and General Manager at Palo Alto Networks, added, "As organizations integrate AI into every aspect of their operations, securing it requires a runtime security platform that provides continuous visibility and real-time insight. Without this, security teams are left in the dark about how AI is being used, misused, or manipulated, which puts critical data and decisions at risk. Prisma AIRS empowers teams with answers to essential questions, like whether someone is exploiting an LLM to extract sensitive information or if a compromised API is feeding the model poisoned data. These insights are vital to maintaining trust and safeguarding AI."
Palo Alto Networks indicated that Prisma AIRS would be enhanced by the company's plans to acquire Protect AI. The acquisition is subject to customary closing conditions and is expected to be finalised in the first quarter of the company's fiscal 2026. Protect AI focuses on securing the use of AI, aligning with Palo Alto Networks' efforts to address AI security concerns comprehensively.

‘Nanogirl' informs South on AI's use
Even though "Nanogirl", Dr Michelle Dickinson, has worked with world leading tech giants, she prefers to inspire the next generation. About 60 Great South guests were glued to their Kelvin Hotel seats on Thursday evening as the United Kingdom-born New Zealand nanotechnologist shared her knowledge and AI's future impact. Business needed to stay informed about technology so it could future-proof, she said. The days were gone where the traditional five year business plan would be enough to futureproof due to the breakneck speed technology has been advancing. Owners also needed to understand the importance of maintaining a customer-centric business or risk becoming quickly irrelevant. "I care about that we have empty stores." The number of legacy institutions closing was evidence of its model not moving with the customer. "Not being customer-centric is the biggest threat to business." Schools were another sector which needed to adapt to the changing world as it predominantly catered to produce an "average" student. "Nobody wants their kids to be average." Were AI technology to be implemented it could be used to develop personalised learning models while removing the stress-inducing and labour-intensive tasks from teachers' workload. "Now you can be the best teacher you can be and stay in the field you love. "I don't want our teachers to be burnt out, I want them to be excited to be teaching." In 30 seconds, new technology could now produce individualised 12-week teaching plans aligned to the curriculum, in both Ma¯ori and English she said. Agriculture was another sector to benefit from the developing technology. Better crop yields and cost savings could now be achieved through localised soil and crop tracking information which pinpointed what fertiliser needs or moisture levels were required in specific sections of a paddock. While AI was a problem-solving tool which provided outcomes on the information available to it, to work well, it still needed the creative ideas to come from humans, she said. "People are the fundamentals of the future . . . and human side of why we do things should be at the forefront. "We, as humans, make some pretty cool decisions that aren't always based on logic." Personal and commercial security had also become imperative now there was the ability to produce realistic "deep-fake" productions with videos and audio was about to hit us. She urged families and organisations to have "safe words" that would not be present in deep fake recordings and allow family members or staff to identify fake from genuine cries for help. "This is the stuff we need to be talking about with our kids right now." Great South chief executive Chami Abeysinghe said Dr Dickinson's presentation raised some "thought-provoking" questions for Southland's business leaders. She believed there needed to be discussions about how Southland could position itself to be at the forefront of tech-driven innovation. "I think some of the points that she really raised was a good indication that we probably need to get a bit quicker at adopting and adapting. "By the time we get around to thinking about it, it has already changed again." AI was able to process information and data in a fraction of the time humans did, but the technology did not come without risks and it was critical businesses protected their operations. "If we are going to use it, we need to be able to know that it's secure." Information on ChatGPT entered the public realm that everyone could have access to and business policies had not kept up. "You absolutely have to have a [AI security] policy."

Nearly half of developers say over 50% of code is AI-generated
Cloudsmith's latest report shows that nearly half of all developers using AI in their workflows now have codebases that are at least 50% AI-generated. The 2025 Artifact Management Report from Cloudsmith surveyed 307 software professionals in the US and UK, all working with AI as part of their development, DevOps, or CI/CD processes. Among these respondents, 42% reported that at least half of their current codebase is now produced by AI tools. Despite the large-scale adoption of AI-driven coding, oversight remains inconsistent. Only 67% of developers who use AI review the generated code before every deployment. This means nearly one-third of those working with AI-assisted code are deploying software without always performing a human review, even as new security risks linked to AI-generated code are emerging. Security concerns The report points to a gap between the rapid pace of AI integration in software workflows and the implementation of safety checks and controls. Attacks such as 'slopsquatting'—where malicious actors exploit hallucinated or non-existent dependencies suggested by AI code assistants—highlight the risks when AI-generated code is left unchecked. Cloudsmith's data shows that while 59% of developers say they apply extra scrutiny to AI-generated packages, far fewer have more systematic approaches in place for risk mitigation. Only 34% use tools that enforce policies specific to AI-generated artifacts, and 17% acknowledge they have no controls in place at all for managing AI-written code or dependencies. "Software development teams are shipping faster, with more AI-generated code and AI agent-led updates," said Glenn Weinstein, CEO at Cloudsmith. "AI tools have had a huge impact on developer productivity, which is great. That said, with potentially less human scrutiny on generated code, it's more important that leaders ensure the right automated controls are in place for the software supply chain." Developer perceptions The research reveals a range of attitudes towards AI-generated code among developers. While 59% are cautious and take extra steps to verify the integrity of code created by AI, 20% said they trust AI-generated code "completely." This suggests a marked difference in risk appetite and perception within developer teams, even as the majority acknowledge the need for vigilance. Across the sample, 86% of developers reported an increase in the use of AI-influenced packages or software dependencies in the past year, and 40% described this increase as "significant." Nonetheless, only 29% of those surveyed felt "very confident" in their ability to detect potential vulnerabilities in open-source libraries, from which AI tools frequently pull suggestions. "Controlling the software supply chain is the first step towards securing it," added Weinstein. "Automated checks and use of curated artifact repositories can help developers spot issues early in the development lifecycle." Tooling and controls The report highlights that adoption of automated tools specifically designed for AI-generated code remains limited, despite the stated importance of security among software development teams. While AI technologies accelerate the pace of software delivery and updating, adoption of stricter controls and policy enforcement is not keeping up with the new risks posed by machine-generated code. The findings indicate a potential lag in upgrading security processes or artifact management solutions to match the growing use of AI in coding. Developers from a range of industries—including technology, finance, healthcare, and manufacturing—participated in the survey, with roles spanning development, DevOps management, engineering, and security leadership in enterprises with more than 500 employees. The full Cloudsmith 2025 Artifact Management Report also explores other key issues, including how teams decide which open-source packages to trust, the expanding presence of AI in build pipelines, and the persistent challenges in prioritising tooling upgrades for security benefits.
