It seems that remote working won’t go away after the pandemic passes. In fact, organisations in most industries are working towards making it a permanent and viable option. 

Large enterprises and corporations like Facebook and Google plan to keep the model for a while. While others like Twitter, Slack, and Zillow decided to allow (most or all of) their employees to work from home permanently. Their decision-making points towards the likeliness of remote work becoming a permanent option in most companies.  

SMBs looking to secure work from home 

According to Intermedia’s survey, small to medium business owners believe the remote work model will stay permanently. The survey indicates there is an overwhelming preference in keeping remote work as a long-term option. With 57% of SMB owners stating that employee availability and life and job satisfaction have increased, and citing a drop in overhead costs as a benefit that enabled them to stay afloat during lockdowns. 

Those SMBs deciding to embrace the model are in the midst of preparations to make remote work permanent. 

The Microsoft 365 suite is heavily used among SMBs, as their subscription model offers industry-leading functionality at a reasonable price. With access to security and operational features previously available only to enterprises, Microsoft 365 also includes cloud-based services that can be used from anywhere. Making the suite a perfect choice for work-from-home teams. 

Compliance remains a core concern for work-from-home protection

Remote work comes with a new set of risks, especially for cybersecurity. Compliance acts and regulations don’t differentiate between in-office and remote work. 

They require that you have secure working-from-home policies for sensitive information and data, and that you secure staff when working from home. 

The most common regulations to comply with include: 

  • Health Insurance Portability and Accountability Act (HIPAA) for businesses offering health services 
  • EU’s General Data Protection Regulation (GDPR) for all businesses processing and handling personal data from EU citizens
  • California Consumer Privacy Act (CCPA) for all California-based businesses and those doing business in California
  • Canada’s Personal Information Protection and Electronic Documents Act (PIPEDA) for everyone handling personal data from Canadian citizens

These acts require you to comply with Information Security Management Systems (ISMS) standards, most notably the ISO/IEC 27000 series, as well as the Payment Card Industry (PCI) Data Security Standard (DSS) for those who take card payments online. 

SMBs often struggle with acquiring the right security solutions because the budgets are low. 

Remote work and software spending

The graph below shows how expectations on software spending have changed from March to May 2020. 

As the impact of the pandemic stopped being an unknown variable, respondents have revised their expectations on spending, which is indicated by less spending than initially expected.

While the highest percentage of respondents (40%) initially stated they will increase their spending on software, in May, 44% reported there were no changes compared to spending during the previous year. 

And while the overall spending seems to stay the same, there are big shifts on what type of software the funds are allocated to.

With working from home being the new norm, conferencing takes the lead, followed by collaboration, remote desktop tools, and security software. 

Work-from-home protection is an important concern for SMBs, and as the newest data from Microsoft shows, everyone is trying to speed up their cybersecurity digital transformation. 

So how can you protect all the Microsoft 365 documents and communication that you work with daily when everyone is using different networks and devices to access it?

How to protect Microsoft 365 when working from home

In our experience, the most efficient option to cover both of these is to use Advanced Microsoft Information Protection (MIP), as it has the best cost-benefit ratio. 

Microsoft Information Protection uses built-in capabilities from Microsoft Office 365 and Windows 10, as well as additional solutions provided by Microsoft, to secure Microsoft 365 and all the digital information and data you work with in your business across the whole playing field: in the cloud by using Cloud App Security, as well as on devices and on premises. 

It allows you to detect sensitive information and locate where it’s currently stored, secure documents as soon as they are created, and even ensure that you dispose of them in a secure manner. 

What Microsoft Information Protection can do for SMBs: 

  • It will secure Microsoft 365 apps and services you use and all your business information from leakage.
  • It blocks malicious actors from access, and doesn’t allow access to untrusted actors.
  • The automatic classification protects all documents based on the criteria, trigger words, and phrases you set up. 
  • It actively tracks data through its lifecycle and gives you insight into who has access to data and a log of who accesses it and what they are doing with it.
  • It helps your employees stay productive and learn about working from home best practices. The system will suggest labels and teach them how to use and apply them correctly. 
  • It gives you overview over information flow, with valuable insight on patterns of data usage inside of your organisation. 
  • This allows to spot anomalies in data usage and access, enabling quick detection of potentially harmful actions by actors or malicious software.
  • It keeps all data secure even when sharing with vendors and third parties by not allowing forwarding, downloading, or copying information shared with them.

Such capabilities extend beyond securing your data – it also keeps your staff secure from making errors while handling data, and all the vendors you work with by not allowing them to forward any information you share with them further. 

Once set up, you’ll have a system that performs well in the cloud, covering the need to secure remote working, but on premises too, once you decide to go back into the office.

Why you need to secure Microsoft 365 for remote working

When you secure Office 365, you and your team can do remote work securely and are saving time and money. But that’s only one benefit of using such an extensive system: 

  • No changes in workload: The automatic classification and encryption of all documents you work on and share with remote staff, contractors, and other third parties means there is no need to increase workload for your staff and spending time on complex manual security checks that they need to learn to apply. 
  • You will secure Microsoft Office through compliance: Classification and encryption executes on the cloud level too and protects against human error, one of the most common reasons behind data leaks. Securing Microsoft 365 for remote working also helps you be compliant with all regulations. 
  • Security travels: The cloud-based protection extends beyond business devices – the protection remains with documents and data and travels with them, ensuring they are secure even if they end up in the wrong hands. 

Secure external consultant documents for Microsoft 365

Working with external consultants increases risk of data leakage and breach, since you are relying on them to practice good cybersecurity. 

Instead of hoping they are doing a good job, you can secure Microsoft 365 documents sent to and used by external consultants through MIP. With auto classification, the options for downloads and further sharing will be disabled, ensuring the data can never be accessed by anyone but your external consultants. 

Secure internal sensitive and confidential information when working from home

Secure Microsoft 365 data with MIP’s extensive labeling and trigger system based on labels. You can classify all information into specific categories, and set up sensitivity labels for each of those categories. 

The trigger system activates based on the rules you set up. For each rule, there is a condition that must be met in order to trigger the second part, the action, something that will happen automatically when the condition is matched. 

For example, when a user without permission tries to access a sensitive document, the rule sends an email to the user and administrator of your system about the incident. 

Whenever someone creates a new document, no matter where within your organisation, it will automatically be protected based on the category and labels applied to that type of document. 

These labels are document-based, meaning they persist with it and are transferred anywhere the document ends up. If the document ends up being in an insecure environment, your security policies will continue being enforced, and won’t allow usage by anyone who isn’t a trusted source. 

The system allows you to track all data and documents as it moves through and outside of your organisation. In case you ever suspect foul play, you will be able to revoke access to the document, rendering it useless to anyone who is trying to get it. 

In such cases, the MIP can, based on your setup, respond with a real-time email alert, or a report on the dashboard.

Microsoft Information Protection includes Data Loss Prevention (DLP) capabilities, with policies against accidental sharing. With it, you can also label documents for information retention, set an expiry time and apply deletion policies that will execute automatically when requirements are met. 

Secure email communication when working remotely

The labeling system goes beyond Office apps, and you can secure Microsoft Outlook in the form of Office 365 Message Encryption. 

It allows you to classify and secure email messages as well. When labeled, the policies for that specific label will be applied to the email. This includes policies such as: 

  • Encryption
  • Watermarks
  • Access restriction
  • Disabling forwarding

The label that is applied will persist with the email and keep security policies on the email even when it leaves your organisation. It helps employees work from home securely by preventing phishing attacks and disclosing information accidentally. 

Secure BYOD for remote working

By having online-only work, your employees will use a number of devices to access business data, like Windows and Mac OS machines and mobile devices. A comprehensive security suite such as Microsoft Information Protection has encrypting standards that will work on all of them. 

If you’re unsure on the right way to secure BYOD for remote working and set up policies, we can discuss other ways of working with BYOD. For example, we offer Windows Information Protection setup services that secure employee-owned devices from data leakage and other security incidents. 

The MIP setup takes time and IT knowledge

Microsoft Information Protection is definitely an all-encompassing solution that addresses the risks of remote work well. It secures access to sensitive data and documents, grants permissions to the right stakeholders, and ensures all your business data is safe even if it’s somehow accessed without authorisation. 

But there is a downside to it: It takes a lot of time to set up such an extensive system for someone who never had to deal with it. Even if you have an IT professional on your team, chances are, they will need to ask for help. Only those with knowledge in Active Directory, a good comprehension of Microsoft licensing, and previous experience with Microsoft or Azure Information Protection itself can set it up. 

One error in permissions and labeling, and you can lock yourself out from your own documents, even if you are the admin. Or if you miss it during setup, the system might not flag important documents correctly, making them easily accessible by someone without permission.
