See the cloud you don't control.
Nexus CASB reveals the SaaS and AI apps your people actually use, scores their risk, governs OAuth access and catches cloud threats — extending your data policy to everything beyond the perimeter.
You can't govern the apps you can't see
Business units adopt SaaS faster than security can approve it, each app granting OAuth access and holding data you're accountable for. The perimeter went to the cloud; most controls didn't follow. Nexus CASB brings the unsanctioned, the misconfigured and the over-permissioned back into view — and under policy.
Shadow SaaS everywhere
Teams sign up for tools in minutes. CASB discovers them from your existing logs and ranks the risk.
SaaS drifts out of posture
Sanctioned apps get misconfigured over time. SSPM checks them against baselines and flags drift.
OAuth is an open door
Third-party apps hold standing tokens into your tenants. CASB surfaces and governs those grants.
Bring the cloud estate under control
Built into Nexus DLP — the CASB composes the same classification and policy engines, so cloud control speaks one language with endpoint and network.
Shadow-IT discovery
Parse proxy and firewall logs to reveal every SaaS and AI app in use, categorised and risk-ranked.
SaaS posture (SSPM)
Assess sanctioned SaaS against security baselines and alert on configuration drift.
OAuth governance
Inventory and govern third-party OAuth grants and app-to-app access to your tenants.
Cloud threat detection
Catch impossible travel, mass download, mass share and OAuth-grant spikes across cloud activity.
GenAI / shadow-AI control
Discover generative-AI usage and keep sensitive content out of prompts with adaptive responses.
Adaptive access
Decide in context — allow, monitor, step-up, limit or block — instead of a blunt all-or-nothing gate.
API-mode and log-based, not another inline choke point
Discovery comes from logs you already produce; posture and governance work through SaaS APIs. The same per-org policy and classification engines drive every decision.
Part of the Nexus DLP build — every CASB engine is hermetic and ships within the 149/149 green self-test gate.
Shadow-IT and GenAI usage surfaced from proxy/firewall logs, categorised and risk-ranked.
SSPM evaluates SaaS posture against baselines; OAuth governance inventories third-party grants.
Cloud threat engines flag impossible travel, mass download/share and OAuth spikes.
Shared DLP classification identifies sensitive data moving to or within cloud apps.
Adaptive access chooses the proportionate response in context.
Outcomes applied consistently with endpoint and network policy.
Discovery without an agent on every app
CASB learns your real SaaS footprint from logs you already generate, then enriches each app with category and risk so you can decide sanction, limit or block.
- Shadow-IT and shadow-AI discovery from existing logs
- Per-app category and risk scoring
- Fold discovered apps straight into policy
- GenAI usage made visible and governable
- SSPM baseline checks with drift alerts
- Third-party OAuth grant inventory and governance
- Cloud threat detection across user activity
- Adaptive, context-aware enforcement
Posture and access, continuously
Beyond discovery, CASB keeps your sanctioned estate healthy — checking posture and governing the OAuth grants that quietly accumulate.
