Most engineers think… Most people assume CASB and DLP mean buying two more products and stitching them into the traffic path. With Cato, that mental model is wrong — and it shows in an interview. Because every site and remote user already flows through the Cato SASE Cloud single-pass engine , CASB and DLP run as features inside that one engine and one policy . CASB discovers sanctioned and unsanctioned apps, scores their risk and applies granular activity and tenant controls; DLP inspects the same traffic for sensitive content and blocks or alerts. There is no separate appliance to chain — the value is that being in-path lets both work together, everywhere, from one rule set. ## ① The problem — SaaS sprawl, Shadow IT and data leaking out Two everyday risks keep security teams up at night. First, SaaS sprawl and Shadow IT : people sign up for cloud apps on their own, so the org has no list of what is in use, which apps are risky, or what data is going into them. Second, sensitive data leaking out — a customer spreadsheet uploaded to a personal cloud drive, payment-card data pasted into a random web app. The traditional fix was bolting on a separate CASB and a separate DLP product, each with its own console and its own place in the path. Cato's advantage is that everything already flows through it. Because every edge routes through the Cato SASE Cloud, the chance to govern SaaS and inspect content is built in — no extra box required. Figure 1 — The converged loop — discover, classify, inspect, enforce CASB and DLP run as one in-path loop against the same Cato single-pass engine and one policy. - The converged loop — discover, classify, inspect, enforce Discover find SaaS in use Classify sanctioned vs risk Inspect DLP data types Enforce allow / alert / block Log event + forensics CASB and DLP run as one in-path loop against the same Cato single-pass engine and one policy. Quick check · Q1 of 10 · Understand Why can Cato offer CASB and DLP without a separate appliance? a) It resells a third-party DLP box b) Because all traffic already flows through the Cato single-pass engine, so both run as features of one policy c) It only inspects email d) It runs entirely on the endpoint Correct: b. Being in-path is the whole advantage: every site and remote user routes through the Cato SASE Cloud, so CASB and DLP are features of that one engine and one policy — no extra box to chain. 👉 So far: Cato CASB & DLP solve SaaS sprawl/Shadow IT and data leakage — and because every edge already flows through Cato, both are built in, with no separate appliance. ## ② CASB — discover apps, score risk, control activity and tenants Since all traffic passes through Cato, CASB can see the cloud apps people actually use and split them into sanctioned (corporate-approved) and unsanctioned / Shadow IT (personal or unapproved). To make decisions by risk rather than by name, Cato maintains a cloud app catalog of thousands of apps, each with a risk score based on security and compliance attributes. ### Controls that aren't all-or-nothing Per app you can allow, block or restrict , and go further with activity-level controls — for example, allow viewing or downloading from an unsanctioned app but block upload , or allow chat but block file sharing. CASB also enforces tenant restrictions : allow the corporate Microsoft 365 tenant while blocking personal tenants of the same app, so nobody signs into a personal instance to move data out. Figure 2 — Bolt-on CASB + DLP vs Cato in one engine Two stitched-in products and consoles versus CASB and DLP as features of the same single-pass engine. Bolt-on CASB + DLP vs Cato in one engine Bolt-on products Separate CASB and DLP boxes Two consoles to reconcile Each placed in the path Inconsistent per site Cato (one engine) CASB + DLP in single pass One unified policy Already in-path for all Same for every edge Two stitched-in products and consoles versus CASB and DLP as features of the same single-pass engine. Figure 3 — CASB controls, least to most granular Cato CASB goes well beyond block-the-whole-app to action and tenant-level control. CASB controls, least to most granular Allow / block app Per-app decision by name or risk Restrict by risk Gate on the app catalog risk score Activity control Allow view, block upload or file share Tenant restriction Corporate tenant yes, personal no Cato CASB goes well beyond block-the-whole-app to action and tenant-level control. 🔎 CASB tap to flip Discovers cloud/SaaS apps inline, splits sanctioned vs unsanctioned (Shadow IT), scores app risk, and applies activity and tenant controls. 🛡️ DLP tap to flip Inspects content for built-in data types (PII, PCI, PHI, financial, secrets) plus custom patterns, and blocks or alerts on uploads/downloads. 🕶️ Shadow IT tap to flip Unsanctioned, unapproved apps employees adopt on their own — surfaced by CASB because all traffic passes through Cato. 🏢 Tenant restriction tap to flip A CASB control that allows your corporate tenant of an app while blocking personal tenants of the same app. Lead with activity controls, not whole-app blocks In an interview, don't say 'block the app'. Say you discover apps, score risk from the catalog, then apply granular activity controls (allow view, block upload) and tenant restrictions (corporate tenant yes, personal no). That is the difference between governance and a blunt firewall. Quick check · Q2 of 10 · Apply You want to let staff read files from an unsanctioned cloud drive but stop them uploading company data. Which CASB capability fits? a) Block the whole app b) Disable TLS inspection c) An activity-level control — allow view/download, block upload d) Delete the app from the catalog Correct: c. Activity-level controls act on specific actions inside an app, so you can allow viewing/downloading while blocking upload — instead of an all-or-nothing app block. 👉 So far: CASB discovers sanctioned vs unsanctioned apps, scores risk from a cloud app catalog, and applies allow/block/restrict, granular activity controls and tenant restrictions. ## ③ DLP — inspect content for sensitive data, then block or alert DLP inspects the actual content moving over the web and SaaS apps for sensitive data. It ships with built-in data types — PII, PCI / payment-card , PHI / health, financial and secrets/credentials — plus custom patterns and dictionaries (keywords and regex) you define for your own data. On a match, DLP controls the action — block or alert (monitor) — on both uploads and downloads , across the web and SaaS apps. Crucially, DLP is part of the same single-pass engine and the same unified policy as the rest of Cato; there is no separate DLP appliance to deploy or chain. You write a data-protection rule in the one place every other rule lives. Figure 4 — One policy, both signals A single Cato rule can combine the CASB app/tenant/activity signal with the DLP content signal for every edge. One policy, both signals One policy single-pass engine App discovery Risk scoring Activity controls Tenant restrictions DLP data types TLS inspection A single Cato rule can combine the CASB app/tenant/activity signal with the DLP content signal for every edge. 'DLP is just a keyword blocklist' under-sell Cato DLP uses built-in data types (PII, PCI, PHI, financial, secrets) and custom patterns/dictionaries, with block or alert on uploads and downloads across web and SaaS — all in one policy. Reducing it to 'a keyword filter' misses that it converges with CASB and runs in the same single-pass engine. ### ▶ Watch a PII upload to a personal cloud drive get blocked How one upload is inspected end-to-end by CASB and DLP together. Press Play for the healthy path, then Break it to see the classic failure. ① Upload An employee tries to upload a spreadsheet of customer PII to a personal cloud-drive account. ▼ ② Decrypt TLS inspection decrypts the HTTPS upload so Cato can read the SaaS activity and the file content. ▼ ③ Identify + inspect CASB flags an unsanctioned app on a personal tenant; DLP detects PII in the file content. ▼ ④ Block + log The combined CASB + DLP verdict blocks the upload and logs the event with user, app and data type. Press Play to step through the healthy block path. Then press Break it . ▶ Play Next ▶ ⚠ Break it ↺ Reset Quick check · Q3 of 10 · Remember Which is a built-in Cato DLP data type? a) A BGP route b) PCI / payment-card data c) A switch port number d) A DHCP lease Correct: b. Cato DLP ships built-in data types for PII, PCI/payment-card, PHI/health, financial and secrets/credentials, plus custom patterns and dictionaries you define. 👉 So far: DLP inspects content for built-in data types (PII, PCI, PHI, financial, secrets) plus custom patterns, blocking or alerting on uploads/downloads across web and SaaS — in the same single-pass engine and one policy. ## ④ Converged in one policy — every edge, TLS, and tuning The real power is that CASB and DLP are converged . One rule can decide an action from both signals at once: block uploading any file containing credit-card numbers to an unsanctioned cloud drive. CASB identifies the app, tenant and activity; DLP inspects the content; the combined verdict acts. And because it is part of SASE, the same policy applies to all edges — every site and every remote user — with no per-location config. ### The dependency and the pitfalls All of this rests on TLS inspection : SaaS and web traffic is HTTPS, so Cato must decrypt it to see activity and file content. No TLS inspection = no visibility , and both CASB activity controls and DLP go blind. The other classic mistakes: using all-or-nothing app blocking instead of activity controls, and turning on broad DLP data types without tuning , which buries real incidents under false positives. Start in alert/monitor, tune, then promote to block. Sneha at a Hyderabad fintech faces this Despite a Cato DLP rule meant to stop customer PII leaving, a finance analyst uploads a customer spreadsheet to a personal cloud drive and nothing is blocked or logged. Likely cause TLS inspection is not enabled for that user group, so Cato sees only encrypted traffic and can't read the SaaS activity or the file content — CASB and DLP are effectively blind. Diagnosis In the Cato Management Application the CASB & DLP rule shows zero hits for that app, and the user group is excluded from TLS inspection. Cato Management Application ▸ Security ▸ TLS Inspection + CASB & DLP rules Fix Enable TLS inspection for the group (with a sensible bypass list for cert-pinned apps), set the CASB rule to block personal tenants of the cloud-drive app, and set the DLP rule on the PII data type to block on upload; start in alert to baseline, then promote to block. Verify Re-test the upload: CASB flags the unsanctioned personal-tenant app, DLP detects PII in the file, the upload is blocked and logged, while legitimate sanctioned-app traffic still flows. Prove it with TLS on and a test upload Never assume a DLP rule works. Confirm TLS inspection is enabled for the group, then run a controlled upload of a benign test file containing the data type. Watch the rule hit and the event log. If there is no hit, TLS inspection or the data-type scope is the first suspect. Quick check · Q4 of 10 · Analyze A Cato DLP rule isn't firing on SaaS uploads at all. What should you check first? a) The office Wi-Fi password b) Whether the endpoint is charged c) The DNS server d) Whether TLS inspection is enabled for that user group Correct: d. SaaS traffic is HTTPS. Without TLS inspection Cato sees only encrypted bytes, so it can't read the activity or file content — both CASB controls and DLP go blind until decryption is on. 👉 So far: CASB + DLP converge in one policy across all edges and depend on TLS inspection; avoid all-or-nothing blocking and untuned data types — start in alert, tune, then block. ### 🤖 Ask the AI Tutor Tap any question — instant, scoped to this lesson.

Q5 · Understand What makes Cato able to converge CASB and DLP into one product? a) A dedicated DLP appliance per site b) A separate cloud for each function c) All traffic already flows through one single-pass engine and policy d) An agent installed on every server Correct: c. Cato is in-path for every edge, so CASB and DLP are features of the same single-pass engine and unified policy — that convergence is the core idea, not two stitched-together products. Q6 · Remember In CASB, what is 'Shadow IT'? a) Unsanctioned / unapproved apps users adopt on their own b) The corporate-approved app list c) The admin audit log d) An encryption mode Correct: a. Shadow IT is unsanctioned, unapproved apps employees start using on their own. CASB surfaces them because all traffic passes through Cato, then scores their risk. Q7 · Apply You must allow the corporate Microsoft 365 tenant but stop users signing into personal M365 to move data out. Which control? a) A broad DNS block b) Turn off TLS inspection c) A blanket bandwidth limit d) A CASB tenant restriction Correct: d. Tenant restrictions allow your corporate tenant of an app while blocking personal tenants of the same app — exactly this case. Blocking DNS or the whole app would break legitimate corporate use. Q8 · Analyze Why can one Cato rule block uploading a card-number file to an unsanctioned cloud drive? a) Each function uses its own separate console b) Because CASB (app/tenant/activity) and DLP (content) converge in one policy and decide together c) Because the file is unencrypted d) Because the endpoint agent does it locally Correct: b. Convergence is the point: CASB identifies the unsanctioned app, tenant and upload activity, DLP inspects the content for PCI data, and the combined verdict acts — in a single rule, one policy. Q9 · Evaluate Both CASB and DLP suddenly see nothing on SaaS traffic. Most likely root cause? a) DNS cache is stale b) TLS inspection is disabled for those users, so traffic stays encrypted c) The app catalog needs more apps d) Downloads are not inspected by design Correct: b. SaaS is HTTPS; without TLS inspection Cato can't decrypt it, so neither CASB activity controls nor DLP content inspection can see anything. Re-enabling inspection for the group restores visibility. Q10 · Evaluate What is the safest way to roll out a broad new DLP data type in production? a) Block on every match immediately b) Delete matched files automatically c) Start in alert/monitor, baseline and tune the data type and custom patterns, then promote true positives to block d) Disable TLS inspection to reduce load Correct: c. Turning on broad data types straight to Block floods the team with false positives. Alert first, tune the data types and custom patterns/dictionaries, then promote genuine matches to block.

Then compare with the expert version. Compare with expert answer Expert version: Because every site and remote user already flows through the Cato SASE Cloud single-pass engine, CASB and DLP are features of that one engine and the same unified policy — not separate boxes placed in the path. CASB discovers sanctioned and unsanctioned apps, scores their risk and applies activity and tenant controls; DLP inspects the same traffic for built-in and custom data types and blocks or alerts. They converge in one rule across all edges, and both rely on TLS inspection to decrypt HTTPS so they can actually see SaaS activity and file content. ### 🗣 Teach a friend Best way to lock it in — explain it in one line to a teammate.

DLP (Data Loss Prevention) Inspects content for sensitive data types and blocks or alerts on uploads/downloads to stop data leaving. Single-pass engine Cato inspects each packet once and applies all security functions, including CASB and DLP, in that one pass. Sanctioned app A corporate-approved cloud application that the org has chosen to allow. Unsanctioned app / Shadow IT A personal or unapproved cloud app users adopt on their own, surfaced by CASB because traffic passes through Cato. App risk score A rating in Cato's cloud app catalog reflecting an app's security and compliance posture, so you decide by risk. Activity control A granular CASB control over actions inside an app — e.g. allow viewing/downloading but block upload or file sharing. Tenant restriction A CASB control that allows the corporate tenant of an app while blocking personal tenants of the same app. Data type A DLP classifier for sensitive content — built-in (PII, PCI, PHI, financial, secrets) or a custom pattern/dictionary. TLS inspection Decrypting HTTPS so Cato can read SaaS activity and file content; without it CASB and DLP are blind. #### 📚 Sources Cato Networks — CASB (Cloud Access Security Broker) product page . catonetworks.com - Cato Networks — Data Loss Prevention (DLP) product page . catonetworks.com - Cato Knowledge Base — Configuring the CASB / Application Control policy . support.catonetworks.com - Cato Knowledge Base — Configuring DLP data types, content profiles and rules . support.catonetworks.com - Cato Knowledge Base — TLS Inspection configuration and bypass list . support.catonetworks.com - Cato Networks — The Cato SASE Cloud single-pass architecture (SSE 360) . catonetworks.com ### What's next?
