\n\nWhy hybrid working needs new IT investments<\/h3>\n\n\n\n
Hybrid working combines office and home office days, creating new requirements for collaboration, network and security that classic office structures do not cover.<\/p>\n\n\n\n
According to surveys, more than half of employees plan to continue working from home long-term or pursue a hybrid approach. However, this working model comes with complexities for company networks and infrastructures. IT departments need to set new policies and make the right investments to ensure continuous improvements in employee productivity and effectiveness in the hybrid model. Although every company has its own approach and its own infrastructure, the IT requirements are very often similar. To prepare for the hybrid working model, there are always three issues to deal with.<\/p>\n\n\n\n
Investment 1: collaboration tools such as Microsoft Teams<\/h3>\n\n\n\n
Collaboration is made easier, efficiency increases. Collaboration tools ensure that knowledge in the company is made easily accessible and transparent for everyone in a central location at all times. With the help of collaboration tools, e-mail floods are a thing of the past. You can form working groups in which all communication relating to the project can be tracked and all documents used are stored centrally. You can work in these documents in parallel. There are no different versions, the file is always up to date.<\/p>\n\n\n\n
Groups or teams can be created in different “visibilities”: public, managed, closed. This significantly promotes exchange within a team, because collaboration tools make working together so easy. Whether it is a quick question, a vote, a photo, a video or a statement: with the reply function, everyone can easily get involved and react within the “protected” framework of the group or team. This creates new project-oriented networks within the company, increases the visibility of individuals within the company and gives project groups a more pronounced group feeling.<\/p>\n\n\n\n
Investment 2: a modern network with SD-WAN<\/h3>\n\n\n\n
Companies must be able to cope with the heavy use of cloud applications in home offices and the associated changes in their data network. The cloud has provided a lifeline for many businesses during the pandemic. Increasing reliance on the cloud must go hand in hand with the adoption of secure internet breakout and software-defined networking technologies for the office and home office to enable optimized application performance.<\/p>\n\n\n\n
SD-WAN as a software-defined network:<\/strong> SD-WAN<\/a> and shared portals are essential for long-term hybrid working in companies. Companies need a sophisticated SD-WAN solution that prioritizes data traffic and allocates bandwidth optimally. This keeps cloud usage performant and stable without applications slowing down or crashing. Prioritization across network boundaries prevents bottlenecks and protects critical processes. These technologies increase agility, stability and reliability. SD-WAN allows secure prioritization of, for example, video conferences and cloud access (SaaS) directly via the internet.<\/p>\n\n\n\nInvestment 3: security based on Zero Trust<\/h3>\n\n\n\n
Hybrid working has expanded the cyber threat landscape. Combating it has become a top priority for IT managers, and the threat of criminal hacker attacks is looming.<\/p>\n\n\n\n
Home office as a security risk:<\/strong> The basic problem with working from home is that employees use networks that are not under the company’s control. These must initially always be regarded as insecure. It is therefore important to ensure that the connection to the company network and access to company data from these networks is secure.<\/p>\n\n\n\nAttack scenarios in the home office do not differ significantly from those in corporate environments. Employees working from home are more susceptible to such attacks because they cannot quickly ask a colleague for advice when they receive a suspicious email. Instead of taking the trouble to make a request to customer support, they may make the wrong decision themselves.<\/p>\n\n\n\n
Zero Trust as a solution:<\/strong> A Zero Trust architecture<\/a> can provide a remedy here. This assumes that no user, no request and no service that wants to access the company network is trustworthy until it proves otherwise: applications are mapped in the cloud via connectors and can only be used individually by authorized users, without them even having to be in the company network. The legitimate user only sees the application they need to work with. Unlike in the corporate network via VPN, other applications remain hidden and inaccessible. Models such as SASE bundle SD-WAN and Zero Trust access control directly from the cloud.<\/p>\n<\/div>\n<\/div>\n\n\n

Frequently asked questions about home office and hybrid working<\/h3>\n\n\n\nWhich three investments do companies need for successful hybrid working?<\/strong> For successful hybrid working, companies need three central investments: collaboration tools such as Microsoft Teams for transparent teamwork, a modern network based on SD-WAN for stable cloud performance, and a security architecture based on the Zero Trust principle for secure access regardless of location. All three areas interlock: without a stable network, collaboration tools run poorly, and without Zero Trust, access from home remains a security risk. SAVECALL advises companies vendor-neutrally on all three building blocks.<\/p> <\/div>
Why is a classic VPN no longer enough for home office?<\/strong> A classic VPN treats every user as trustworthy after login and often grants access to the entire network. This is risky in the home office, since employees use networks that are not under the company’s control and must initially be regarded as insecure. A Zero Trust approach, by contrast, checks every request individually and only grants access to the specific application needed. Other applications remain hidden and inaccessible. This significantly reduces the attack surface compared to a classic VPN.<\/p> <\/div>
How does SD-WAN help with cloud applications in the home office?<\/strong> SD-WAN prioritizes data traffic and allocates bandwidth optimally, so cloud usage stays performant and stable without applications slowing down or crashing. Video conferences and SaaS access in particular can be securely prioritized directly over the internet instead of routing through an overloaded headquarters connection. Prioritization across network boundaries prevents bottlenecks and protects critical processes. For companies with many home office employees, SD-WAN is therefore a central foundation for stable cloud performance.<\/p> <\/div>
What makes collaboration tools like Microsoft Teams so important for hybrid working?<\/strong> Collaboration tools make knowledge in the company centrally accessible and transparent instead of scattering it across email floods. In working groups, the entire project communication can be tracked, documents are stored centrally, and multiple people can work on them in parallel without different versions arising. Different visibilities for groups and teams further promote exchange. This creates new project-oriented networks within the company and strengthens the sense of team even across locations.<\/p> <\/div>
What does Zero Trust mean in practice for home office employees?<\/strong> Zero Trust means that no user, request or service is considered trustworthy until proven otherwise. Applications are mapped in the cloud via connectors and can only be used individually by authorized users, without them having to be on the company network. The user only sees the application they need for their work. Other systems remain invisible and unreachable, which significantly limits the risk if a device or access is compromised.<\/p> <\/div>
How does a company start modernizing for hybrid working?<\/strong> A sensible starting point is a stocktake of the current collaboration, network and security situation to identify gaps in all three areas. Based on this, a company can prioritize whether an SD-WAN solution, a Zero Trust approach, or better collaboration tools will have the biggest impact first. SAVECALL accompanies companies vendor-neutrally from analysis through selecting the right providers to implementation, creating a secure, efficient and scalable infrastructure for hybrid working.<\/p> <\/div> <\/div>\n\n\n

Why is a classic VPN no longer enough for home office?<\/strong> A classic VPN treats every user as trustworthy after login and often grants access to the entire network. This is risky in the home office, since employees use networks that are not under the company’s control and must initially be regarded as insecure. A Zero Trust approach, by contrast, checks every request individually and only grants access to the specific application needed. Other applications remain hidden and inaccessible. This significantly reduces the attack surface compared to a classic VPN.<\/p> <\/div>
How does SD-WAN help with cloud applications in the home office?<\/strong> SD-WAN prioritizes data traffic and allocates bandwidth optimally, so cloud usage stays performant and stable without applications slowing down or crashing. Video conferences and SaaS access in particular can be securely prioritized directly over the internet instead of routing through an overloaded headquarters connection. Prioritization across network boundaries prevents bottlenecks and protects critical processes. For companies with many home office employees, SD-WAN is therefore a central foundation for stable cloud performance.<\/p> <\/div>
What makes collaboration tools like Microsoft Teams so important for hybrid working?<\/strong> Collaboration tools make knowledge in the company centrally accessible and transparent instead of scattering it across email floods. In working groups, the entire project communication can be tracked, documents are stored centrally, and multiple people can work on them in parallel without different versions arising. Different visibilities for groups and teams further promote exchange. This creates new project-oriented networks within the company and strengthens the sense of team even across locations.<\/p> <\/div>
What does Zero Trust mean in practice for home office employees?<\/strong> Zero Trust means that no user, request or service is considered trustworthy until proven otherwise. Applications are mapped in the cloud via connectors and can only be used individually by authorized users, without them having to be on the company network. The user only sees the application they need for their work. Other systems remain invisible and unreachable, which significantly limits the risk if a device or access is compromised.<\/p> <\/div>
How does a company start modernizing for hybrid working?<\/strong> A sensible starting point is a stocktake of the current collaboration, network and security situation to identify gaps in all three areas. Based on this, a company can prioritize whether an SD-WAN solution, a Zero Trust approach, or better collaboration tools will have the biggest impact first. SAVECALL accompanies companies vendor-neutrally from analysis through selecting the right providers to implementation, creating a secure, efficient and scalable infrastructure for hybrid working.<\/p> <\/div> <\/div>\n\n\n

Three key investments for sustainable productivity<\/h2>\n\n\n\nHybrid working needs collaboration, SD-WAN and Zero Trust together. SAVECALL shows the three key investments.<\/h6>\n\n\n\n
Hybrid working is here to stay. But flexibility alone is not enough: the right technologies are crucial. SAVECALL shows which three investments will make your company fit for the future.<\/p>\n\n\n\n
In a nutshell:<\/strong><\/p>\n\n\n\n The solution:<\/strong> With these foundations, companies can create a secure, efficient and scalable infrastructure for hybrid working.<\/p>\n\n\n\n What this article covers:<\/strong> This article shows the three key investments for successful hybrid working: collaboration tools, a modern SD-WAN network and security based on the Zero Trust principle. The core question: How future-proof is your home office concept?<\/p>\n\n\n\n Hybrid working combines office and home office days, creating new requirements for collaboration, network and security that classic office structures do not cover.<\/p>\n\n\n\n According to surveys, more than half of employees plan to continue working from home long-term or pursue a hybrid approach. However, this working model comes with complexities for company networks and infrastructures. IT departments need to set new policies and make the right investments to ensure continuous improvements in employee productivity and effectiveness in the hybrid model. Although every company has its own approach and its own infrastructure, the IT requirements are very often similar. To prepare for the hybrid working model, there are always three issues to deal with.<\/p>\n\n\n\n Collaboration is made easier, efficiency increases. Collaboration tools ensure that knowledge in the company is made easily accessible and transparent for everyone in a central location at all times. With the help of collaboration tools, e-mail floods are a thing of the past. You can form working groups in which all communication relating to the project can be tracked and all documents used are stored centrally. You can work in these documents in parallel. There are no different versions, the file is always up to date.<\/p>\n\n\n\n Groups or teams can be created in different “visibilities”: public, managed, closed. This significantly promotes exchange within a team, because collaboration tools make working together so easy. Whether it is a quick question, a vote, a photo, a video or a statement: with the reply function, everyone can easily get involved and react within the “protected” framework of the group or team. This creates new project-oriented networks within the company, increases the visibility of individuals within the company and gives project groups a more pronounced group feeling.<\/p>\n\n\n\n Companies must be able to cope with the heavy use of cloud applications in home offices and the associated changes in their data network. The cloud has provided a lifeline for many businesses during the pandemic. Increasing reliance on the cloud must go hand in hand with the adoption of secure internet breakout and software-defined networking technologies for the office and home office to enable optimized application performance.<\/p>\n\n\n\n SD-WAN as a software-defined network:<\/strong> SD-WAN<\/a> and shared portals are essential for long-term hybrid working in companies. Companies need a sophisticated SD-WAN solution that prioritizes data traffic and allocates bandwidth optimally. This keeps cloud usage performant and stable without applications slowing down or crashing. Prioritization across network boundaries prevents bottlenecks and protects critical processes. These technologies increase agility, stability and reliability. SD-WAN allows secure prioritization of, for example, video conferences and cloud access (SaaS) directly via the internet.<\/p>\n\n\n\n Hybrid working has expanded the cyber threat landscape. Combating it has become a top priority for IT managers, and the threat of criminal hacker attacks is looming.<\/p>\n\n\n\n Home office as a security risk:<\/strong> The basic problem with working from home is that employees use networks that are not under the company’s control. These must initially always be regarded as insecure. It is therefore important to ensure that the connection to the company network and access to company data from these networks is secure.<\/p>\n\n\n\n Attack scenarios in the home office do not differ significantly from those in corporate environments. Employees working from home are more susceptible to such attacks because they cannot quickly ask a colleague for advice when they receive a suspicious email. Instead of taking the trouble to make a request to customer support, they may make the wrong decision themselves.<\/p>\n\n\n\n Zero Trust as a solution:<\/strong> A Zero Trust architecture<\/a> can provide a remedy here. This assumes that no user, no request and no service that wants to access the company network is trustworthy until it proves otherwise: applications are mapped in the cloud via connectors and can only be used individually by authorized users, without them even having to be in the company network. The legitimate user only sees the application they need to work with. Unlike in the corporate network via VPN, other applications remain hidden and inaccessible. Models such as SASE bundle SD-WAN and Zero Trust access control directly from the cloud.<\/p>\n<\/div>\n<\/div>\n\n\n SAVECALL helps companies build collaboration, network and security as a coordinated overall concept for hybrid working. We compare SD-WAN and Zero Trust providers vendor-neutrally across more than 80 carriers and manufacturers and find the solution that fits your budget and your team’s IT expertise.<\/p>\n\n\n\n With collaboration tools, a modern SD-WAN network and a Zero Trust security architecture, companies create a secure, efficient and scalable infrastructure for hybrid working. All three investments interlock: if one is missing, the home office concept remains vulnerable or inefficient. The right prioritization depends on the current IT landscape and the available budget.<\/p>\n\n\n\n <\/p>\n\n\n Written by<\/p>\n\n\n\n Key Account Consultant, SAVECALL<\/strong><\/p>\n\n\n\n Has supported companies for over 20 years in selecting and optimizing their connectivity solutions. His focus: making complex telecommunications understandable from the customer’s perspective and strategically finding the right solution.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n <\/p>\n <\/p>\n\n\n <\/p>\n\n\n For successful hybrid working, companies need three central investments: collaboration tools such as Microsoft Teams for transparent teamwork, a modern network based on SD-WAN for stable cloud performance, and a security architecture based on the Zero Trust principle for secure access regardless of location. All three areas interlock: without a stable network, collaboration tools run poorly, and without Zero Trust, access from home remains a security risk.
