Smartphones have long been more than just communication tools: they are fully-fledged work devices and simultaneously open up new attack surfaces for cybercriminals.
Whether at home, on the go or in the office – smartphones and tablets are indispensable in modern working life. Employees read emails, access Microsoft Teams, edit documents or authenticate themselves using mobile devices.
Nevertheless, many companies still focus their IT security on servers, laptops, or networks. Mobile devices are often underestimated – even though they grant access to sensitive company data and pose significant risks if lost or inadequately secured.
In an accompio expert interview, Silas Weißmann explains why mobile device security is an indispensable component of modern cybersecurity today, what role Mobile Device Management (MDM) plays in this, and what measures companies can take to effectively secure their mobile devices.
In this focus topic, our expert Silas Weißmann, IT system consultant at accompio, talks about the security of smartphones and tablets in everyday business life, as well as strategies for modern Mobile Device Management.
The summary follows the official chapters of the YouTube video and editorially condenses the content evidenced in the interview and the article. It is not a verbatim transcript.
00:00 Introduction and mobile device security: Smartphones and tablets are mission-critical work devices. They access emails, cloud applications and sensitive corporate data and therefore belong in the cybersecurity strategy.
00:21 Introduction of Silas Weißmann: Silas Weißmann is an IT systems consultant at accompio and supports companies with the implementation and operation of mobile device management solutions.
01:21 Why smartphones are a security risk: Mobile devices increase the attack surface because they access numerous corporate services and are often managed less rigorously than laptops or servers.
03:30 Risks in everyday business: Lost or stolen devices, weak passcodes, missing screen locks, outdated operating systems, and uncontrolled apps can make access to corporate data easier.
04:41 What Mobile Device Management does: An MDM provides transparency regarding the deployed devices and enables the centralised control of security policies, encryption, passcode requirements, updates and the protection of corporate data.
06:35 Quickly implementable measures: Strong authentication, device encryption, up-to-date operating systems, approved app sources and remote wipe already significantly improve the level of security.
07:38 The human factor in security: Technical safeguards are complemented by clear processes and awareness raising. Employees should be able to recognise phishing and know what immediate action to take if a device is lost.
08:43 Apple and Android: For both platforms, mobile devices should be centrally provided, managed, and secured with binding security policies.
12:03 Updates, manufacturers and device management: Organisations should monitor and actively manage security updates. Platforms such as Apple Business Manager and Android Enterprise support automated deployment and central management.
The world of work is mobile. Emails are answered on smartphones, appointments are coordinated on the go, and documents are accessed via cloud services or collaboration platforms like Microsoft Teams. For many employees, the smartphone is now the device they use most frequently.
This development brings enormous benefits in terms of productivity and flexibility – but simultaneously changes the requirements for IT security. This is because every mobile device that accesses company resources expands the potential attack surface.
In an interview, Silas Weißmann describes this development as one of the biggest changes in recent years. Smartphones are now an integral part of almost every workplace and therefore need to be managed and secured just as professionally as notebooks or desktop PCs.
„Today, smartphones are one of the most important work tools. Nevertheless, their importance for IT security is often still underestimated.„

Cybercriminals aren't necessarily looking for the technically weakest system – they're looking for the easiest entry point. Mobile devices often offer favourable conditions for this if they are not centrally managed or adequately secured.
Crucially, smartphones can now access numerous business services. These include, among others:
If a device is lost or compromised, attackers may be able to access sensitive company information. It is therefore all the more important not to view mobile devices as isolated units, but as an integral part of the company's IT infrastructure.
Contrary to popular belief, many security incidents are not caused by highly complex hacker attacks, but by everyday situations.
In the interview, Silas Weißmann specifically cites the loss of mobile devices as one of the biggest risks. If a smartphone falls into the wrong hands without adequate protection, this can have significant consequences – especially when weak passcodes are used or central security policies are non-existent.
Among the most common risks are:
However, these risks themselves can be significantly reduced with comparatively little effort.
An effective Mobile Device Security begins with transparency. Companies need to know which mobile devices are accessing corporate resources, their security status, and whether defined policies are being adhered to.
Here one begins Mobile Device Management (MDM) It enables IT to centrally manage smartphones and tablets and implement security standards across the company.
For example, an MDM solution can be used to:
This creates a unified security basis – whether a few or several hundred mobile devices are in use.
„Technology should support users, not slow them down. Ideally, good mobile device security works without employees even noticing it in their daily lives.„
— Silas Weißmann, IT Systems Consultant at accompio
However, technology alone is not enough. Mobile device security is particularly effective when technical measures, clear processes, and appropriate security awareness come together.
Employees should know,
A modern security strategy therefore combines technical protective measures with clear guidelines and regular employee awareness training.
„Mobile device management is not an end in itself. It lays the foundations for integrating mobile devices into the organisation’s IT infrastructure securely, efficiently and in a way that can be tracked.„

Would you like to manage mobile devices securely? accompio develops security strategies and solutions for Mobile Device Management that fit your requirements.
Even just a few measures can significantly improve the security of mobile devices.
Companies should, in particular:
These measures provide a solid foundation for sustainable mobile device security and can be implemented regardless of the size of the organisation.
Mobile end devices are an integral part of almost every company's IT today. At the same time, they are among the most frequently underestimated attack surfaces.
Anyone who fails to consistently secure their smartphones and tablets risks unauthorised access to sensitive company data. A professional Mobile Device Management creates the necessary transparency, automates security policies and significantly reduces administrative overhead.
Mobile device security should therefore not be considered in isolation, but as an important component of a holistic cybersecurity and zero-trust strategy. Companies that consistently manage and secure mobile devices not only create more security but also more efficient processes and a better user experience.
Silas Weißmann is an IT Systems Consultant at accompio and supports companies with the introduction and operation of modern Mobile Device Management solutions.
Mobile device security encompasses all technical and organisational measures designed to protect smartphones and tablets from data loss, unauthorised access, malware and other cyber threats.
Mobile Device Management (MDM) is a solution for centrally managing mobile devices. It allows companies to implement security policies, configure devices, manage apps, and remotely lock or wipe lost devices.
Mobile end-user devices access emails, cloud applications, and corporate data. Without appropriate security measures, lost or compromised devices can pose significant information security risks.
MDM allows for the central management of all mobile devices, automates security policies, reduces administrative effort, and improves compliance.
Yes. Provided suitable security policies and MDM solutions are used. These enable, among other things, the separation of private and business data and the centralised management of business applications.
Both platforms support companies in automatically deploying mobile devices, managing them centrally, and implementing security policies during the setup process.
Key measures include strong passcodes, biometric authentication, device encryption, regular updates, Mobile Device Management, and staff awareness training.
Yes, particularly medium-sized companies benefit from standardised security processes, a reduced administrative burden, and better protection of sensitive company data.
