‘We want to become better known for access control’ - Q&A with Bosch Building Technologies’ Gregor Schlechtriem

Gregor Schlechtriem has worked in the access control market for over 20 years and is now responsible for the Access & Intrusion Business Unit at Bosch Building Technologies. In this interview, the expert talks about key industry trends, the impact of the COVID-19 (Coronavirus) pandemic, technical innovations and his company’s strategy.

Mr. Schlechtriem, you have many years of experience in the security technology market. What is your background and what are your responsibilities as Senior Vice President at Bosch Building Technologies?

Gregor Schlechtriem: I am a trained engineer and electrical technician, and have been involved with access control in the broadest sense, since I started my career in the late 1980s. I started in the field of parking garage technology and then switched to security technology in 2001, as Managing Director of micos GmbH, which specialised in traditional access control.

micos GmbH was known for its highly available and highly secure access control systems, for critical infrastructure and government applications. Many systems from that time are still in use today and continue to be supported and upgraded.

Bosch is continuing micos’ business here?

Gregor Schlechtriem: Exactly, micos was taken over in 2004 by Bosch Security Systems, now known as Bosch Building Technologies. Since then, we have continuously been developing the access control business.

Being part of the Bosch Building Technologies division, we benefit a lot from international cooperation with colleagues

Being part of the Bosch Building Technologies division, we benefit a lot from international cooperation with colleagues and from overlap with other product lines, such as intrusion detection technology and video security. This gives us the opportunity to implement outstanding project solutions for demanding customers in an international environment.

In developing this business, I rely on my experience from other interesting roles at Bosch that I took on, after micos was bought in 2004. For a time, I worked in the European System Integrator Business, which I also had the privilege of managing for several years, as well as being directly responsible for business units.

In Fairport, USA, I had the overall responsibility for intrusion detection technology for many years, as I later did in Eindhoven for video systems. Since 2018, the global access control and intrusion detection business has once again been my direct responsibility.

At Bosch Building Technologies, we have in the meantime assigned sales to the respective business units, so that we can develop our product and solution portfolio, in close cooperation with sales and our regular customers. Our main task now is to make our access control portfolio accessible to a broader market. We want to make Bosch much better known, as an access control provider, in the international market. After all, with our own access product portfolio, the power of the Bosch Group and over 40 years of experience in this sector, we have a lot to offer.

As an expert in access control, how do you see the industry developing? In which direction is it currently evolving?

Gregor Schlechtriem: First of all, I see that security requirements are constantly increasing. Whereas there are currently still simple ‘key replacement systems’ that merely record card numbers, such an approach, to a large extent, no longer meets today’s security and user experience requirements.The core task of access control has not changed over the years

In the beginning, access control was more or less a kind of key replacement. Later, there was the possibility of increasing security via a pin code, i.e., via verification through simple data inputs. The next step in this direction was biometrics, which is another key step up, because it allows verification by means of unmistakable characteristics.

However, the core task of access control has not changed over all the years and has basically always remained the same: access control means determining who has an access request and checking whether this request can be fulfilled.

What’s next on this path to greater security?

Gregor Schlechtriem: Biometrics-based access control is becoming increasingly powerful and user-friendly through the use of artificial intelligence (AI). Here, data protection plays a major role, as wherever identities are established and movement data is recorded, it is necessary to reconcile the evolving technology with data protection.Biometrics-based access control is becoming increasingly powerful and user-friendly through the use of artificial intelligence

The question of data protection is becoming even more significant, as systems increasingly migrate to the Cloud. Bosch puts particular emphasis on ensuring that, even in the cloud, the data generated in access control is always in line with data protection rules, regardless of where it is located.

In my opinion, this trend towards the Cloud will continue, because companies are increasingly looking for complete service offerings, so that they can focus on their core business. Also, a system in the Cloud is easier to maintain and always up-to-date with the latest software, which makes cloud solutions even more attractive for providers and users.

How can higher security be reconciled with a good user experience?

Gregor Schlechtriem: Today, the card still plays a central role in the user experience, as the essential credential. Another current trend is ‘one card for everything’: with the increasing availability of secure multi-function smart cards, the possibility arises to use cards beyond the pure access function, for example, for payment in the canteen, at the catering and coffee machines, and in the parking garage, as well as simple access to other properties and so on.The security of cards has evolved significantly and kept pace with requirements

The security of the cards, the reading and encryption processes, has evolved significantly and kept pace with requirements, although we are also facing an installed base that no longer meets these requirements, due to outdated systems.

Today, it is standard for communications between reader and card to be encrypted. In some cases, the keys are also only held centrally to further increase security.

The security systems industry was also affected by the COVID-19 (Coronavirus) pandemic. How do you think the industry has changed? What technical solutions have emerged during this time?

Gregor Schlechtriem: First of all, there is a certain need for retrofitting in the industry due to changes in how buildings are used. For example, American retailers used to be open around the clock and always had staff on site. Now, due to COVID-19, stores are also closed, and this results in a whole new need for intrusion detection and access control systems to protect the buildings.

For access control, an obvious task has arisen as a result of the COVID-19 pandemic, namely to track contacts, as far as this is compatible with data protection. We actually expected more to happen here, but in our observation, many companies did quite little, despite clear and simple steps that could have been implemented relatively quickly. The installed access control systems clearly lag behind the technical possibilities.

Another topic that the COVID-19 pandemic has brought into focus is hygiene

Another topic that the COVID-19 pandemic has brought into focus is hygiene. Companies should actually have invested in contactless systems here and retrofitted speed gates or motorised doors. But in many cases this was not put into practice.

The door opener is still often used, which has to be operated manually and therefore, is touched multiple times. But, if everyone presses the same button, that doesn't help hygiene. Surprisingly, this is different in North America.

Here, ‘request-to-exit’ proximity detectors are used almost everywhere, which avoids this problem completely and releases the door, when an authorised person approaches it.

Mobile access and smartphone-based access control are also growing markets. What kind of developments do you see in these areas?

Gregor Schlechtriem: I already mentioned that users increasingly want to be able to use one card for several applications. But, what we are seeing here is that even with the most modern cards, which have a lot of applications loaded on them, we are reaching performance limits and the user experience suffers.

If you compare the card with the smartphone as a credential, you have a much more attractive integration platform there, which is significantly faster and delivers much better performance. For us, the mobile credential or the smartphone is the future, because it simply offers more possibilities that the card will not be able to provide in the long term.

What is the specific direction Bosch is taking here?

Gregor Schlechtriem: We are currently working on a broad implementation. A whole team is working on the user experience around the smartphone, because it’s understood that smartphone-based access has to work just as easily, as it currently does with a card.A whole team is working on the user experience around the smartphone

In theory it does, but if you look at some of the actual implementations, this topic is still relatively complex. In terms of user experience and automation, we still have quite a way to go, and we are working hard on that at the moment.

The user experience is one side of the coin, the other side concerns establishing security in the smartphone as a whole. In other words: How do I make the smartphone secure enough as a mobile credential, to meet my access control requirements? We are also working intensively on this.

That's actually an IT task. Do you do this yourself at Bosch or do you work with external experts here?

Gregor Schlechtriem: We have our own powerful Bosch IT, which also manages our company smartphones. If our company smartphones are lost, the data on them is automatically deleted.

The devices use biometrics to identify users, before they can access the data. It is a sound security concept that a card cannot offer. Moreover, we are working with other partners in the IDunion project, to create the additional infrastructure around mobile credentials as well.

What exactly is the IDunion and what role does Bosch play?

Gregor Schlechtriem: Digital identities must be openly accessible, widely usable, interoperable, and secure. This applies not only to access control, but to the digitised economy in general. The IDunion project has set itself the task of creating the infrastructure for this, in the form of an independent wallet, i.e., secure identity storage on smart devices.

The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWI), because digitisation is also a critical social issue. We are intensively involved in the ‘Physical access to the building’ work package in this consortium. Through this involvement, we want to ensure that our access control systems benefit from this infrastructure and are open to future digital business models.

Does ‘digital identity management’, which includes biometrics and mobile access, also play a role for Bosch?

Yes, it plays an important role for us, and I wouldn’t consider these topics separate

Gregor Schlechtriem: Yes, it plays an important role for us, and I wouldn’t consider these topics separate. For me, a mobile device has the advantage that it has already ensured and verified my identity from the moment of interaction. That’s the fascinating thing about it. If I only allow the device to communicate with the access control system, if I have identified myself first, I have implemented biometrics and access control together in a widely accepted process.

From my point of view, this is a very interesting perspective, in terms of security and user experience, because the biometrics procedures in smartphones are, I think, the best currently available. In my view, the smartphone has the potential to take over central functions in access control in the future.

What are your goals for the access control business of Bosch Building Technologies in the near future?

Gregor Schlechtriem: We will continue to focus on specific solutions for large customers. That is the continuation of our current strategy. In these projects, we will introduce new topics as I have just described, i.e., primarily new technology elements. I believe that, precisely because of the longevity of access control, a long-term migration capability is also of particular importance.

We want to reach out to the broader market and make more widely available, what we have developed in terms of technology and innovation. We are currently in the process of setting up and optimising our sales organisation, so that it becomes much more widely known that we at Bosch have our own powerful access control portfolio, which can be used for all kinds of applications.

In addition, we want to differentiate ourselves in the market with our systems, in line with the motto of our founder, Robert Bosch: ‘Technology for life’. The user experience with Mobile Access should be simple, straightforward, and secure: You hold your smartphone in front of the reader and the door opens.
