In today’s hyperconnected, cloud-first world, enterprises are no longer fighting yesterday’s cyber battles. Threat actors have evolved and so have their tools. Modern cyberattacks are faster, more automated, and increasingly powered by artificial intelligence (AI). Unfortunately, many organizations are still relying on security models that were designed for a different era—one with defined perimeters, fewer entry points, and simpler adversaries.
According to Accenture, 68% of business leaders believe their cybersecurity risks are increasing, yet 60% still depend on legacy systems that lack real-time responsiveness and AI-enhanced capabilities. In this blog, we explore why legacy security can’t keep up with modern threats—and how C1 and Palo Alto Networks are working together to help enterprises modernize their defenses with AI-driven, end-to-end protection.
Legacy cybersecurity tools were built around the concept of a perimeter. But today, the perimeter has all but disappeared. With hybrid work, cloud migration, SaaS sprawl, and third-party integrations, the enterprise attack surface is now everywhere.
And attackers know it.
Modern threats are leveraging automation, generative AI, and malware-as-a-service platforms to scale and evolve at unprecedented rates. According to IBM’s Cost of a Data Breach Report, the average breach lifecycle is 277 days. However, threat actors using AI can reduce this to under a week. AI-generated phishing emails now have a 54% open rate compared to 12% for human-written ones (ExplodingTopics), and AI-assisted ransomware attacks have grown 37% year-over-year (Check Point Research).
Simply put: threats move faster than human teams can respond.
Legacy security systems typically rely on:
These systems can’t see across the modern attack surface, nor can they detect subtle signals that indicate a breach is in motion. Worse, they generate high volumes of false positives, overloading security teams and causing critical alerts to be missed or delayed.
A Gartner report found that by 2025, 75% of organizations using legacy security operations models will suffer business-impacting breaches due to limited visibility and delayed response.
If attackers are using AI, the “good guys” must do the same.
Palo Alto Networks, a global leader in next-generation cybersecurity, has built its Precision AI™ engine to level the playing field. By embedding machine learning, behavioral analytics, and generative AI across its platforms, such as Cortex XSIAM, Prisma Access, and ZTNA 2.0, Palo Alto delivers:
For example, Cortex XSIAM reduces incident response times by up to 98% and automates triage for thousands of alerts daily, without human intervention. This is the type of speed and scale required to defend modern enterprises.
Even the best tools need expert hands to realize their potential. That’s where C1 comes in.
C1’s Advisory, Professional, and Managed Security Services are designed to help enterprises not only deploy Palo Alto’s industry-leading technologies but also align them with operational goals, regulatory requirements, and business outcomes.

C1’s consultants assess your environment to identify gaps, prioritize risk, and build a Zero Trust and AI-readiness roadmap aligned with your business strategy.
C1 Professional Services
C1 designs and deploys Palo Alto’s solutions, including Cortex XSIAM, Prisma Access, and NGFW, while ensuring seamless integration into your environment.
C1 Managed Services
C1 offers 24/7 threat monitoring, policy enforcement, incident response, and ongoing optimization—so your internal teams can focus on strategic priorities while C1 ensures continuous protection.
Together, C1 and Palo Alto Networks don’t just modernize your technology, they modernize your security operations.
Organizations that have transitioned from legacy tools to modern, AI-driven security with C1 and Palo Alto Networks have reported:
These results aren’t theoretical—they’re proof that legacy security doesn’t stand a chance in today’s environment, but modern solutions do.
Modern cybersecurity is no longer about guarding a static castle. It’s about protecting a dynamic, borderless, cloud-based enterprise against increasingly intelligent and persistent threats. Relying on legacy systems is like bringing a filing cabinet to a data breach.
The modern SOC needs automation. It needs visibility. And it needs a team behind it that understands how to translate tools into outcomes.
C1 and Palo Alto Networks offer a fully integrated solution for the AI-era:
Whether you’re looking to replace legacy VPNs, improve threat detection, or build a fully modernized SOC, C1 and Palo Alto Networks are ready to help.
