Protecting your organization against cyber threats is not a matter of installing the most expensive security products on the market. It starts with understanding your own business and security needs: how they shape your infrastructure, which components are involved, how each of them can be attacked and how you can protect it. The right solution answers your specific needs and gets the different pieces to work together, balancing security and usability so your employees actually use it.
Cybersecurity is the use of technologies, processes and controls to protect corporate assets, including computers, networks, software, mobile endpoints and sensitive data, from cyber threats. The products fall into four groups that answer different questions: endpoint management (which devices do we have, and are they configured correctly?), data protection (is our data safe at rest, in use and in transit?), access control (who may access what, and under which conditions?) and threat protection (is something attacking our endpoints right now?). No single product covers all four.
Mobile Device Management (MDM), also called Enterprise Mobility Management (EMM) and today mostly Unified Endpoint Management (UEM), gives you visibility and control over the devices that interact with your infrastructure. A user's mobile device can be provisioned with services such as corporate Wi-Fi and VPN access and with apps, while policies enforce security settings, define what can be done on the device and allow you to act if it is lost or stolen. Reporting shows which devices are active and which services are used, which helps optimize licenses and costs. What a UEM can prevent on its own is covered in Best Practice: Get the Most out of Your UEM.
Corporate data needs protection in three states: in transit, in use and at rest.
Data in use and at rest is protected on the device with encryption. Depending on the device manufacturer, you can encrypt data for a single app or a group of apps (app containerization), for a part of the device (a work profile or workspace) or for the whole device. Where private and work data share a device, enforce Data Loss Prevention (DLP) policies that control which data, if any, may pass between the two.
Data in transit is protected by a secure path to your corporate resources and services, wherever they are hosted, on premises or in the cloud, and wherever employees access them from, so the data cannot be intercepted, read or tampered with.
Virtual Private Network (VPN) technology has been a proven solution for years: for home office users, for connecting remote offices of the same organization and for private use, for example to avoid geo-blocking. Most vendors also use it to connect mobile devices, either the whole device or only some apps (per-app VPN). Some vendors provide their own secure network infrastructure for mobile devices and apps, which is even more transparent for the user.
With the rise of Software as a Service (SaaS), many enterprises host a large part of their IT, sometimes all of it, in the cloud. Zero Trust Network Access (ZTNA) provides a secure, controlled path to both on-premises and cloud resources, so you keep visibility and control over all of them, whether internal or on the open internet. ZTNA is one building block of a Zero Trust architecture.
Access control makes sure only the right people get access to the right resources, as securely and transparently as possible, from any desktop or mobile device. This is the domain of Identity and Access Management (IAM), which focuses on authentication and authorization.
Authenticating users with a password is not enough, because credentials can be stolen or guessed. Multi-factor authentication (MFA) adds information that only the user can provide at that moment. There are several variants, such as two-factor authentication (2FA) and two-step verification, all based on the same concept. Phishing-resistant methods such as FIDO2 security keys and passkeys are the strongest option today.
Once a user is authenticated, Role-Based Access Control (RBAC) and corporate policies determine which resources and services that user may access. In a CRM used to process sales orders, for example, a salesperson may create new orders while a manager reviews and approves them. Conditional Access adds further conditions at sign-in, such as device compliance, location and risk level.
To protect against malware, detect suspicious activity and respond to attacks, you need behavior-based threat defense. Instead of relying on a list of known malicious files like traditional antivirus software, it watches what happens on the system and detects changes in behavior that could indicate a threat. On mobile devices these solutions are called Mobile Threat Defense (MTD), on desktops and servers Endpoint Protection Platform (EPP).
This takes a lot of computing power and data. Artificial intelligence (AI), machine learning (ML) and big data help process the enormous amount of telemetry, find the needle in the haystack that could be an attack and stop it before it does damage.
Endpoint Detection and Response (EDR) continuously collects data from endpoints into a central data store, where it is analyzed to discover threats and respond in real time. EDR not only protects endpoints from advanced attacks but also provides analytics and forensics: you can investigate an incident after the fact, see how an attack unfolded before it was stopped, or search for suspicious activity such as processes started from a script or DNS requests to specific servers. Extended Detection and Response (XDR) applies the same idea across endpoints, network, identity and cloud. EPP, EDR and MTD are explained in more depth in Demystifying Security: EPP, EDR and MTD.
The sound approach to cybersecurity looks at the whole picture: your infrastructure, all its components and the ways each can be attacked. Endpoint management gives you an overview and control of your devices. Data needs protection in all its states, and access must be limited to the right people through MFA, RBAC and Conditional Access. Endpoint protection detects what gets through anyway.
MDM manages mobile devices. EMM added app and content management. UEM covers all endpoints, including laptops and desktops, in one platform. The terms are often used interchangeably.
A VPN connects a device to a network and often grants broad access once connected. ZTNA grants access to individual applications, on premises or in the cloud, after verifying user and device for each request.
EPP prevents malware from running. EDR records endpoint activity continuously, detects attacks that use legitimate files and tools, and supports investigation and response.
There is no universal order, but you cannot protect what you do not know. An inventory of devices and data, usually through UEM, together with MFA for all users, is a common starting point.
