Toptal is a vast network of tech talent and we currently boast the biggest distributed workforce in the industry. This is a source of pride for many Toptalers, especially our hard-working dev team. Why? Because we make it appear so easy and seamless, and we do it every single day. While a traditional tech company is bound to have a vast infrastructure (loads of office space, servers, standardized equipment, abundant physical and cyber security resources, and so on), we don’t.
We rely on off-the-shelf technology and services. Traditional companies struggle to cope with a small number of BYOD users, but here at Toptal, all our hardware is BYOD. The problem with our platform-agnostic approach and the reliance on a distributed network is self-evident: How can we ensure and maintain security?
It was never easy, but we like a good challenge, and like to stay one step ahead. That’s why we set about designing multiple authentication and onboarding procedures last year. We used the first quarter of 2016 for trials and pilots, and they were encouraging. As a result, we decided to announce the results of our trials and unveil our rollout plans.
By the end of the third quarter, all Toptalers will be acquainted with our new solutions, and if all goes well, they will start using them by the end of the year.
How do we make sure everyone logged onto our network is who they claim they are? Most of our team members have never met in real life, yet they collaborate on a daily basis. What if someone’s security has been compromised? Or, what if a disgruntled member decides to undermine the network?
We settled on a twofold approach to addressing these concerns:
- Including a set of personal reliability tests to our screening process.
- Introducing a new layer of biometric security.
What sort of tests will we institute? Our approach was inspired by the Personnel Reliability Program (PRP), created by the U.S. Department of Defense. The program is designed to identify personnel with the highest degree of reliability, taking into account their prior conduct, trustworthiness, behavior, and allegiance. PRP compliance will be evaluated continuously by our newly formed Internal Security Division (ISD), staffed by military intelligence veterans from Israel and Bosnia.
Platform access will be limited to individuals who meet stringent PRP criteria, however, failure to meet these standards will not be grounds for termination or demotion. It will merely reflect the individual’s lack of suitability for certain roles, restricting their access to confidential information.
To ensure continuous compliance, every Toptal member will be required to sign a new non-disclosure agreement and undergo evaluation. The agreement will include provisions covering the treatment of confidential information and outline a set of sanctions for individuals in violation of said agreement.
Since we are a distributed network, we will also rely on input from our members. Our existent monthly TopTeam reports will be expanded to include a personal reliability questionnaire. In other words, each network member will be able to report suspect coworkers or behavior via an anonymous evaluation form.
Lt. Col. David Finci, Head of Toptal’s Internal Security Division, explains the decision to include anonymous ‘tips’:
“Our goal is not to encourage dissent and create friction among team members, but we are convinced this is vital to ensuring personal reliability. We must allow network members to scrutinize the professional performance and personal integrity of their coworkers. Otherwise our ability to source actionable, time-sensitive information would be compromised.”
Network members with full PRP clearance will be issued security tokens and one-time pads to ensure encryption should the integrity of our network is compromised. They will also receive ID cards featuring a scannable QR code and/or barcode.
Use of these security measures will be mandatory, and loss or theft of ID cards will be taken seriously. Fortunately, these cards will be an interim solution and will be phased out as soon as our new security platform is deemed ready. We expect an early 2017 release.
Biometrics: Imperfect Marriage Of Convenience
We started experimenting with quasi-biometric security last year, quite by accident. After one Toptaler decided to tattoo our logo on their arm, we realized this approach could be employed for QR codes. Nobody wants to carry around yet another card in their wallet, and QR codes are relatively small and so they can be easily tattooed, or even engraved on fingernails.
You may be wondering whether or not we are serious, and the answer is obviously no. However, Graham’s tattoo gave us a good idea: Why not use biometric technology, backed by off-the-shelf tracking solutions?
We are already moving towards a passwordless future, and Toptal wants to be on the cutting edge. Why burden people with passwords, silly QR codes, two-factor authentication, or security tokens, if we can ensure superior security without any of them?
There have been attempts at this before, using personal technology such as smartphones and fingerprint scanners, but these techniques aren’t bulletproof. (In the case of smartphone fingerprint scanners, they can be beaten by a simple inkjet printer or knife.)
Besides, using smartphones for authentication opens up a Pandora’s box of other issues.
Bluetooth LE: Rendering Personal Security Bulletproof And Seamless
A lost phone is a recipe for disaster, and with all due respect for all the anti-theft and anti-loss technology out there, much of it doesn’t work well, or requires user input to do its magic. Besides, why rely solely on smartphones when we need to authenticate people on their office hardware?
A lost phone is called a lost phone for a reason, because the user is unaware that it’s lost to begin with. If you wake up and realize you lost your phone last night, it’s too late. That said, if you have a habit of waking up at strange places without your phone, or any recollection of the night before, you should also be on the lookout for kidney theft.
This is where it gets interesting. Security tokens and dongles work, but they’re a pain to carry around, and they have a habit of getting lost at the worst possible moment. That is why we planned for our ID cards to be a temporary measure, only active for 9 months or so. We intend to replace them with inexpensive, wearableBluetooth devices.
Yes, Toptalers will be required to carry them on their person at all times, but this won’t be a problem. Bluetooth LE is a killer technology, at least in terms of power consumption, and these devices can be secured with relative ease, providing a new layer of authentication (we can’t discuss the details due to NDA restrictions).
We initially tried a number of cheap fitness trackers and anti-loss tags to prove our approach was feasible. It worked, but these off-the-shelf devices were not ideally suited to our needs, so we set about designing our own, which proved to be surprisingly easy.
Enter The Toptal TopBand
We reached out to a number of reputable Chinese OEMs for consultation and technical input. We provided them with the specs, they provided us with their quote and a shipping date. Yes, it was that simple, and yes, we were pleasantly surprised.
We are currently in the process of going through several different Toptal TopBand designs and form factors, as well as working on the software side. These devices will not only interface with your phone and computer as wireless security tokens, they will also track your work and sleep habits.
Why? Because they can. They are based on hardware used in fitness trackers, so we didn’t need to reinvent the wheel and design the hardware from scratch. In fact, it would cost more to remove unnecessary features and sensors than to use off-the-shelf solutions.
Here are the specifications of our initial product:
- Bluetooth 4.0 chip manufactured by Dialog
- Accelerometer from ADI
- 50mAh lithium polymer battery by Sony, 40-day battery life
- Vibration assembly, three LED UI, notification speaker
- Dimensions: 8mm x 15mm x 35mm (estimate)
- Weight: 8g (estimate, without strap or clip-on)
We have not finalized the design yet, so the physical dimensions are just estimates. We are still in the process of deciding whether to use aluminium or polycarbonate for the housing, or a combination of both (we want it to look insanely cool). Either way, the device will be IP67 weather resistant, so you don’t even have to take it off when you hit the shower.
This is why we are convinced the device won’t be a nuisance. It’s tiny, you don’t have to charge it every other day, it can be carried as a standard fitness tracker on the wrist, keychain, and it can even fit in your wallet (as an added bonus, it can be used to alert users if they misplace their wallet or keys).
Of course, you could just pair it to your computer as wireless security device and forget about these features, but where’s the fun in that?
Here is what the TopBand brings to the table, allowing users to:
- Secure their hardware by limiting access to our platform if the TopBand is not paired and in range of the device.
- Locate misplaced phones, or vice versa (use a phone to find the TopBand).
- Receive notifications, via vibration and audio alarms.
- Collect physical activity data, which can be used to prevent burnout and keep track of your work habits (when used as a wearable).
The last point may prove controversial, but might be useful in some circumstances. For example, it will allow your team members to know whether or not you are awake and working, and it’s perfect for time tracking. Naturally, Toptal will not collect or use this data without prior consent. It’s there for your convenience; use it to improve your health and boost productivity.
Toptal Pet Project
While we were tinkering with the prototypes, a few Toptalers decided to create a potential spin-off, a pet project of sorts and when we say “pet project,” we literally mean pet project. A lot of our people are obsessed with their four-legged friends, so they went about devising ways of using our hardware in ways we did not expect: they turned the TopBand into a pet tracker.
The hardware was ready, so all it took was some tweaked code. We encouraged them to test the device on their pets; the data collected would prove valuable if only to ensure that unethical developers couldn’t cheat the system by mounting the TopBand on their cat and telling everyone they are at home, hard at work.
Pet-specific functionality is still being tested, but the results are encouraging. For the time being, the devices monitor basic activity, check whether or not your pet is asleep, and vibrate if the your pet strays out of range. It sounds a bit more humane than those nasty electric shock collars, doesn’t it?
Since cats and dogs come in all shapes and sizes, the biggest problem is sensor calibration, which the team is working on. The device was tested on a few cats, including a morbidly obese Italian feline, and dogs ranging from Jack Russells’ to Akita Inus.
Beyond that, we cannot reveal many details, and here is why; our developers have turned their pet project into a serious endeavour. They approached a few potential investors and secured funding for a limited commercial rollout (also scheduled for 2017), but this is just the first step towards a full pet product line.
Our team is already working on the next generation pet tracker, based on proprietary hardware, with wireless charging and the ability to be used as a subdermal implant.
Sounds Geeky, But Your Pets Will Love It
Subdermal implants have a bad reputation, but most of it is unjustified and peddled by conspiracy cranks. If you ask any pet professional, they will tell you that animals larger than a rat don’t even notice them, and in fact, they tend to be safer and more comfortable than most smart collars. Microchipping is already a widely supported practice globally to minimize stray pet populations; this just takes it one step further.
Until now, subdermal implants were limited to rudimentary RFID functionality and this limited their appeal. This isn’t a swipe at RFID tech; a lot of legit companies are working on RFID implants, and Dangerous Things is one startup that stands out in terms of innovation.
However, Qi wireless charging assemblies are getting smaller and cheaper with each new generation. This, obviously, allows engineers to design feature-packed implants because they can afford to use more battery power for sensors and always-on Bluetooth connectivity.
Unfortunately, we are still not there, and the first prototypes won’t be ready until 2018 at the earliest. Our hardware partners also informed us they won’t be able to conduct animal trials in mainland China, due to the country’s strict and inflexible animal rights legislation.
Therefore, the devices will be tested in Cambodia. We were assured the research would be ethical, so there’s nothing to worry about. Our team is eager to try out the implants on their own pets, and they wouldn’t dream of doing anything that would put their furry bundles of joy at risk.
If It’s Good Enough For My Dog…
This is where we hit a minor snag. Thanks to Toptal’s gung-ho culture, two of our team members volunteered to have the implants tested on them, not just their pets. While it’s still too early for human trials, it goes to show that people might not mind using subdermal implants, provided they can trust the technology. Since these individuals played a pivotal role in the development of our TopBand, they are eager to prove the concept. We are told it sort of gets under your skin after a while.
We need human subjects to test wireless charging and a few other features, as attempts to train cats and dogs to sit in one place for hours are unlikely to work. We settled on an alternative approach for the pilot stage, whereby the animals could still move around and recharge their implants, but this involves strapping a big powerbank and Qi charger mat to the animals. As an interim solution, we plan to make good use of ‘cat condo’ cages and catnip to prove the concept over the course of a few hours.
Human trials are still a long way off, and they require more planning and regulatory oversight. While this approach works for new drugs, we don’t have the time or resources necessary for clinical trials. However, our volunteers agreed to sign a waiver and have the implants installed anyway. Since this could create legal issues in the EU or US, they managed to find a small, Brazilian plastic surgery clinic willing to do the job. The clinic also offered a generous discount on gynecomastia procedures.
Toptal is looking for more volunteers, and there is no doubt in my mind that we will find them. After all, Google managed to find thousands of people eager to pay $1,500 for a useless wearable, only to stop development months later, and they still called it a success! These brave Explorers didn’t even mind being called Glassholes by the interwebs.
As one Toptal volunteer put it:
“I’d rather have an implant the size of an avocado in my groin, than Google Glass on my face!”
