Cisco
Application
AI assistant for contact-centre agents and supervisors that produces call and transfer summaries, live transcription, suggested chat replies, topic analytics, automatic CSAT scoring and agent burnout signals.
AgenticOps workspace where teams and AI agents collaborate to investigate, correlate and resolve issues across domains: natural-language querying, multi-step agent workflows, shared real-time visibility, and native Cisco plus third-party tool integration via Cloud Control Studio.
End-to-end AI security product that discovers an organisation's AI assets, red-teams models and applications for vulnerabilities, and enforces runtime guardrails against prompt injection and data leakage.
Agentic support intelligence delivered inside Cisco Support and Professional Services — 'the delivery vehicle for everything Cisco Support and Professional Services knows about your environment, made continuously available before you ask for it' — generally available as SaaS since April 2026 and included with existing support contracts.
AI-native workforce engagement suite for contact centres that forecasts demand and optimises shifts, uses NLP and LLMs to evaluate 100 percent of human and AI agent interactions (AI Quality Management), and runs performance coaching and AI-led onboarding simulations.
Zscaler
Application
Governance layer for employee use of generative AI that discovers shadow AI applications, applies allow, block or coach policies per user, and monitors prompts and responses against more than 100 data loss prevention dictionaries to stop sensitive data leaving through AI tools.
AI security posture management that auto-discovers and classifies AI models, agents and services across Azure AI Foundry, Amazon Bedrock, Google Vertex AI and unmanaged providers, correlates the sensitive data connected to them, and maps findings to frameworks including NIST AI RMF 600-1 and the EU AI Act.
Runs AI models over the security data flowing through the Zero Trust Exchange, using attack graphs, user risk scoring and threat intelligence to score the probability of a breach, forecast an attacker's next tactics, and recommend policy changes before the attack completes.
AI-driven detection and diagnosis of digital-experience issues across the network and application delivery path.
No counterpart
Cisco sells these in a stack layer with no product recorded for Zscaler yet — nothing on the other side to compare them against.
AI agent
Autonomous customer-service AI agent that handles inquiries conversationally across voice, SMS, email, chat and messaging apps and escalates to a human agent with context when it cannot resolve.
Hardware
Pre-validated modular AI infrastructure bundles that combine Cisco UCS servers, NVIDIA GPUs, Nexus 9000 400G/800G switching and management software into single orderable stacks for AI inferencing, training and fine-tuning.
Turnkey on-premises AI appliance that runs real-time speech transcription for Cisco collaboration deployments locally, for customers with data-sovereignty requirements that rule out cloud AI services.
Cloud-managed full-stack AI cluster sold as hardware plus software plus service, packaging Cisco 6000 and N9300 series switches on an 800GbE back-end fabric, UCS servers with NVIDIA H200 GPUs and BlueField DPUs, optional VAST storage and NVIDIA AI Enterprise under the Hyperfabric cloud controller.
Unified programmable networking-silicon architecture for AI, hyperscale, data-centre, service-provider and enterprise routing/switching, spanning five series (G/P/E/K/A) of chip families.
Zscaler sells these in a stack layer with no product recorded for Cisco yet — nothing on the other side to compare them against.
API service
Real-time guardrails for LLM traffic that inspect prompts and responses inline to block prompt injection, jailbreaks, sensitive-data leakage and toxic or off-topic output, deployed either as a proxy or as an API-based Detection as a Service.
Inline, AI-powered sandbox that analyzes unknown files in real time to block zero-day and file-based malware before it reaches endpoints, using AI/ML models trained on 600M+ samples.
Developer tool
Automated adversarial testing for AI applications and agents that runs simulated attacks using 25+ predefined and custom probes across text, image, voice and document inputs, scoring results for security, safety, hallucination and business alignment against MITRE ATLAS, NIST AI RMF and the OWASP LLM Top 10.
Platform
Cloud-native security platform that inspects and enforces policy on every connection between users, devices, workloads and AI agents, rather than trusting anything on a corporate network.
