Secure Remote Collaboration | SUMāTO

In a matter of weeks, teams across LATAM went from sharing documents in the conference room to editing them simultaneously from ten different locations. Remote collaboration stopped being a perk of tech companies and became the everyday way of working. The problem is that many organizations enabled tools at the speed of urgency, without pausing to ask who has access, what is being shared, and where the information flows out. That gap between adoption and control is, today, the leading source of risk.

In short: Remote collaboration tools are secure when identity, permissions, and sharing are governed with intent. The risk isn't in the cloud or the chat, but in unverified access and in the shadow IT that grows when people solve things on their own. Strong identity, MFA, and clear policies are the foundation.

Why remote collaboration changes the security model

In the office, the perimeter was physical and network-based: whatever was inside was assumed to be trusted. Distributed work dissolves that perimeter. Now the unit of control isn't the wall or the corporate firewall but the identity of each person and the device they connect from.

This means that every access to a video call, a file repository, or a shared board is a security decision. When those decisions are made well, collaboration flows without unnecessary friction. When they are made poorly -or not made at all- forgotten access, public links, and accounts no one reviews pile up.

The three risks that grow most with distributed work

Not all risks carry the same weight. In practice, three account for most incidents in remote collaboration environments:

• Ungoverned access: users with more permissions than they need, accounts belonging to people who have changed roles or left, and credentials reused between personal and corporate services.
• Excessive sharing: "anyone with the link can view" links that end up indexed or forwarded, folders shared with external domains with no expiration, and sensitive files that move to uncontrolled services.
• Shadow IT: tools adopted by teams without going through IT. They arise in good faith -to solve something quickly- but stay off the inventory, unbacked up, without verified encryption, and with no one overseeing them.

The common pattern is a lack of visibility. You can't protect what you don't know exists, nor revoke access that no one recorded.

Identity as the first control

If you could invest in only one layer, it should be identity. A centralized directory -a single place where accounts are created, modified, and deactivated- makes onboarding or offboarding a person a controlled act rather than a scattered trail across ten platforms.

On that foundation, single sign-on (SSO) reduces the number of passwords each person has to manage and, with it, the temptation to reuse them. Fewer passwords mean a smaller attack surface and instant revocation: deactivating one identity closes, all at once, every door connected to it.

MFA: the barrier that stops most attacks

Multi-factor authentication (MFA) requires, in addition to the password, a second factor: a notification on the phone, a temporary code, or a physical key. It is, by far, the control with the greatest return relative to its cost. A stolen credential is no longer enough to get in.

A few practical recommendations when deploying it:

• Prioritize phishing-resistant factors: authenticator apps and security keys are more robust than text-message codes, which are vulnerable to interception and SIM-swap fraud.
• Make it mandatory, not optional: MFA only protects when it covers the whole organization, starting with privileged accounts.
• Mind the experience: use conditional access so the second factor isn't requested on every action, but when the context warrants it -a new device, an unusual location. That way security doesn't become an obstacle people try to dodge.

Designing an identity and MFA scheme tailored to the business is a central part of our cybersecurity practice.

Governing sharing without slowing collaboration

The goal isn't to block but to give context and limits to each act of sharing. A good configuration makes the secure option the easiest option:

• Expiration by default: links and external access should expire automatically unless there's an explicit justification.
• Restriction of public links: limit open-access links and favor sharing with identified people or domains.
• Information classification: distinguish what can leave from what never should. When a document knows its sensitivity level, the rules can enforce themselves.
• Periodic access review: schedule a recurring review of who has access to what. What was granted six months ago is rarely still necessary.

Configuring these controls in cloud and collaboration platforms, without turning every task into red tape, is exactly the kind of balance we address in our cloud projects.

Bringing shadow IT out of the shadows

Shadow IT isn't fought by banning; it's fought by understanding it. When teams adopt tools on their own, it's almost always because the official options don't meet their real need or are too cumbersome.

A strategy that works has three moves:

• Discover: identify which services are actually being used, through network logs and cloud application visibility tools.
• Enable alternatives: offer approved tools that meet that need with an equally good experience. Secure adoption comes from a good alternative, not from a ban.
• Support: provide a simple channel for teams to request new tools and get a quick response. When asking is easy, going around the process loses its appeal.

A secure adoption roadmap

Enabling collaboration with control doesn't require halting operations. It pays to advance in stages:

• Lay the identity foundation: centralize accounts, enable SSO, and make MFA mandatory.
• Order the sharing: define policies for external links, expiration, and classification.
• Gain visibility: map shadow IT and consolidate scattered tools.
• Sustain over time: establish access reviews, monitoring, and ongoing training for teams.

Each stage reduces risk immediately and sets the stage for the next, without asking the organization to stop.

Frequently asked questions

Doesn't MFA slow down daily work?

Implemented well, it's barely noticeable. With conditional access, the second factor is requested only when the context warrants it, not on every login. The cost is seconds; the benefit is stopping the vast majority of unauthorized access.

Is it safe to store sensitive information in the cloud?

Yes, when it's configured well. Serious providers offer encryption and robust controls, but the responsibility for defining permissions, sharing, and access falls to the organization. The cloud is only as secure as the policies you apply to it.

How do I know if I have a shadow IT problem?

If you can't confidently list every tool your teams use to collaborate, you probably do. A discovery exercise over network logs usually reveals several services no one had inventoried.

Where do I start if resources are limited?

With identity and MFA. They are the highest-impact controls at the lowest cost, and they benefit the entire organization immediately without needing to replace the tools you already use.

The first step

Remote collaboration is here to stay, and with it the responsibility to enable it with control. The best starting point is an honest assessment: who has access, what is being shared, and which tools live off the radar. From there, a phased roadmap turns urgency into a solid, lasting capability. At SUMāTO we help LATAM organizations walk that path without slowing the operation. Let's talk about your next step.
