Information Security & Firewall for companies in Criciúma - SC

Why firewall and SD-WAN in Criciúma

The city's profile — regional center of southern Santa Catarina, with industry tied to the ceramics and apparel hub, plus services, retail, and logistics — produces networks that stretch: head office and warehouse, factory and sales office, store and back office, local unit and regional branch. Every one of those extensions creates one more edge to protect and one more path between networks that need to talk without blending into each other.

The firewall answers the first part: what comes in, what goes out, what one segment can reach in another. SD-WAN answers the second: how the locations connect to each other and to headquarters in a managed way, with the policy defined once and applied everywhere.

The provisional edge that stays

The router handed over by the carrier solves the connection and solves nothing else: no segmentation, no access control aligned with the rest of the company, no central visibility. Since the operation works, regularizing it carries no urgency — and the provisional edge consolidates, one location at a time.

The result, after a few expansion cycles, is a company with one security policy on paper and several in practice: each address running whatever equipment circumstance allowed, configured by whoever was available that day. The real protection of the whole becomes that of its most improvised location.

The exposure window

One detail makes the picture worse: the most vulnerable period of a new location is precisely its beginning — default credentials still active, rules left open "for testing," remote access granted to the installer and never revoked. It is the window between going live and being integrated. The more expansions a company runs, the more often that window repeats — and it only stops existing when integration into the policy stops being a task for afterwards.

The new location is born inside the policy

This is where SD-WAN changes the logic of expansion. With the policy defined centrally, the new location's equipment is prepared before the inauguration: it arrives at the address with segmentation, access rules, and the connection to headquarters already defined. Integration stops being a project and becomes a procedure — and the exposure window disappears from the growth cycle.

The same holds for maintenance: a rule change made once applies to every location, instead of demanding a configuration round address by address, with the risk of missing one.

Coverage and response times in Criciúma

Edge management is remote, with response within 45 minutes — rule adjustments, blocked-traffic diagnostics, event analysis. When the equipment itself needs hands on it, on-site response in Criciúma comes within 8 hours: the city is among ASSIST's most active service areas, with coverage across Centro, Próspera, Pinheirinho, Santa Bárbara, and Jardim Maristela and extension to the registered nearby cities of Tubarão and Palhoça.

The sectors that drive demand in the city

In industry, the priority is separation: production equipment must not share a segment with the administrative network, and a vendor's access to a specific machine has to be restricted to that machine. In logistics and retail, the weight falls on integrations with third-party systems and on the operational network that cannot stop. In services, the axis is access — who reaches what, from where, with which credential — in offices that work with client data.
