Information Security & Firewall for companies in Brusque - SC

Why firewall and SD-WAN in Brusque

The city's typical environment grew in stages, and the network edge usually reflects that: the router the carrier left behind, a rule created to solve some long-forgotten problem, the showroom Wi-Fi hanging off the same segment as the management system. It works — until the day a problem in one area crosses over into the others.

A managed firewall replaces that arrangement with a single, administered edge: segments defined by purpose, documented rules, logging of what comes in and goes out, and someone responsible for keeping the whole coherent as the environment changes.

Separating the sale, the production line, and the public

Segmentation in Brusque follows a recurring design. The payment and management network — checkouts, fiscal document emitter, server — sits in a protected segment with minimal exposure. Production sits isolated: industrial equipment running legacy systems that cannot be patched should be reachable neither from the sales floor nor from the internet. And the public Wi-Fi delivers internet access, and nothing else — no route into the other segments.

That separation also protects in the opposite direction: an incident on the open Wi-Fi, which is by nature the most exposed segment, dies there instead of reaching the checkout.

The link as a precondition of the sale

When the sale depends on the network, a single link is a quantifiable risk: the cost of one hour of downtime on a Saturday. SD-WAN addresses it with two or more links from different carriers and automatic failover — losing one does not interrupt the operation, and priority traffic, such as payments, is steered over the healthiest path at any given moment.

For operations with a head office and a store in different cities of the valley, the same technology connects the sites with encryption and traffic prioritization, under a single policy, without depending on manual configuration at each end.

Coverage and response times in Brusque

Management is continuous and primarily remote, with response within 45 minutes; physical intervention happens within 8 hours when required. Brusque is a city where ASSIST genuinely operates, serving the registered neighborhoods — Centro, Santa Terezinha, Azambuja, Jardim Maluche, and São Luiz — and neighboring Blumenau, Itajaí, Balneário Camboriú, and Itapema.

The sectors that drive demand in Brusque

Retail leads, given the direct dependency between network and revenue. Industry follows, driven by the need to isolate production equipment. Logistics requires secure integration with third-party systems — carriers, shippers — and services companies need secure remote access for people working away from the office.

How we run the deployment

It starts with a survey of the current edge: contracted links, equipment, existing rules, and the actual paths between segments — which rarely match the imagined ones. From the survey come the segmentation design and the rule policy, reviewed with the client before anything changes.

The cutover happens in an agreed window, with a rollback plan. After it, the service becomes continuous management: every new rule documented, the edge device kept updated, the policy reviewed periodically, and reporting on what was blocked and what changed.
