Librem 13: Still The Most Secure Laptop Yet

Christian Cawley Updated 24-10-2019
Our verdict of the Librem 13:
A slimline ultraportable MacBook rival with the tightest security and privacy you'll see on any commercially available computer, the Librem 13 is one of the most stunning laptops you'll ever use. Unique security features push the price up, but if you're happy to use Linux, this is ideal.

Concerned by failings in digital privacy and security? Feel as though you’re constantly at the mercy of cybercriminals, creepy corporations, and sinister government departments? Your data is vital: you are the product. Short of going offline, there’s nothing you can do about it.


Or is there?

Linux hardware manufacturer Purism has released a pair of laptops with a focus on security. The Librem 13 and Librem 15 run the PureOS distro, and feature hardware security features.

To find out more, we got hold of the Librem 13, a lightweight ultrabook that retails direct from Purism for $1399.00.

We’ll be looking at the Librem 13’s security and privacy credentials later. At this stage, however, you should know that it has Trusted Platform Module (TPM), a special chip that adds security features.

You’ll also find two kill switches, which we’ll look at below.

In the box is a power supply and a Quick Start Guide. I’ve had a few brand-new laptops over the past decade, and I can’t remember that last time I saw such a guide, so this is a welcome inclusion from Purism.


Purism? Who?

Registered as a Social Purpose Corporation, Purism was founded by Todd Weaver in 2014 and manufacturers devices with a focus on three important values:

  1. Software freedom
  2. Computer security
  3. Internet privacy

Purism declares that “profit maximization is not the purpose” of its business, but that it cannot have charitable status due to selling hardware and maintaining lines of credit.

To find out more, Purism has published the relevant sections of its Articles of Incorporation. You might be interested in statements such as “The Corporation will only use and distribute free/libre and open source software” and “respects users’ rights to privacy, security, and freedom.”

The Librem 13 laptop is one of several Purism devices designed to this end. They rely on trusted hardware and run without proprietary firmware and drivers. For example, the Librem 13 uses the Coreboot firmware, in place of the Intel Management Engine. It’s basically a lightweight, secure BIOS, the implications of which are outlined on the Purism website.


Does This Linux Laptop Allay Online Security Concerns?

Staying secure online, and safeguarding your privacy, has become as important as ensuring you have the latest device and the fastest internet.

Over recent years, an increasing amount of responsibility for online security has been placed your hands. Beyond the comparatively basic implementations of the latest wireless networking standards, it’s left to you and your operating system to make your PC or laptop secure.

Along with antivirus software, there’s the option of keeping your connection secure with a VPN 11 Reasons Why You Need a VPN and What It Is Virtual private networks can protect your privacy. We explain what exactly they do and why you should use a VPN. Read More and employing a set of habits to ensure you stay safe online.

You know the sort of thing: avoid ransomware, don’t open unsolicited email attachments, don’t share your login details, etc.


But that doesn’t have to be where it ends.

Purism’s website describes the Librem 13 as “The first 13-inch ultraportable designed to protect your digital life”. But what does that mean, and how does the laptop live up to it?

Respecting Your Rights to Privacy and Security

Purism describe the computer as having been “designed chip-by-chip, line-by-line, to respect your rights to privacy, security, and freedom. Every hardware and software component—and everything we do—is in line with our belief in respecting your rights to privacy, security, and freedom.”

This is demonstrated in several ways. Most obvious are the kill switches, mounted on the left side of the notebook, next to the audio port. The two switches are for radio (wireless and Bluetooth) and the webcam and built-in mic.

Librem 13 kill switch

All you need to do is ensure these switches are set to off if you’re not using those features.

Another key security feature is the browser, PureBrowser, which is based on Mozilla Firefox.

Underlying all of this is TPM. The Trusted Platform Module is a chip on the Librem 13 motherboard that helps to integrate various features on the computer. These include GPG encryption, tamper detection, and the kill switches.

It’s a Linux Laptop: Ultra-Secure PureOS

If you’ve used Linux before, you’ve almost certainly used Ubuntu.

Like Ubuntu, PureOS is based on Debian and features the GNOME 3 desktop. However, PureOS is quite different from Ubuntu. While it might look the same, under the hood it’s a bit different.

For example, if you fancied running some games on the Librem 13, you wouldn’t be able to grab them from Steam. The digital distribution service has a Linux version, but it won’t run on PureOS due to the unavailability of some packages.

PureOS Overview

On the other hand, this isn’t a gaming laptop, so that might not kill the deal for you. After all, you could install a different operating system.

While PureOS comes pre-installed on the Librem 13, you can install a whole new Linux operating system. This might be using the entire disk, or dual booting from two partitions. There’s also the option to dual boot using a secondary drive, such as the M.2 disk.

Purism tell us they encrypt the root and swap partitions on the HDD, leaving the /boot partition unencrypted for dual booting.

Better still, if you opted to reinstall PureOS, the default settings re-enable encryption on the root and swap partitions, so no additional configuration is required.

In general, the choice is clear: PureOS for a more secure computing experience, or install a new distro for flexibility.

First use of PureOS requires you to set an encryption password. After this, you won’t be able to boot the laptop without the password, which is separate to the standard user account. This degree of security permeates throughout the Librem 13 experience.

Librem 13 Body and Design

The black anodized aluminum finish on the Librem 13 is cool to touch, giving the laptop a feeling of quality that matches the internals.

With the now-traditional ultraportable wedge shape, the Librem 13 is remarkably slim, measuring just 0.7-inch at the thick end of the wedge. It’s slim enough to fit into all but the most compact of tablet and laptop bags; along with the internals, this fulfills Purism’s description of the Librem 13 as “The Road Warrior.”

As beautiful as the body is, it really attracts finger grease. Within five minutes of opening the Librem 13, you could see exactly where my fingers had been; my palms, too. This is nothing new for anodized aluminum finishes, however, and can be dealt with using a damp, lint-free cloth.

Anodized aluminum attracts skin grease

One of the key weaknesses of laptop computers—beyond the ease with which they can be stolen—is the hinge. If this goes wrong or breaks, the computer is pretty much useless. There are ways to prolong the life of a laptop hinge, such as opening with two hands, one at each corner, or top open slowly from the center of the lid.

Keeping these in mind, the Librem 13 has a “super sturdy hinge” which Purism claims keeps the laptop “shut when shut”. It also keeps the chosen screen angle, anywhere within a 130-degree arc.

Is the Keyboard Fit for Purpose?

When it comes to using the laptop, you’re first presented with a responsive keyboard, comfortable, with everything within easy reach. Sure, there’s no number pad, but the FN button can help there as the number pad keys have been replicated on the right of center of the keyboard.

I have quite large hands, but despite the size of the computer (noticeably smaller than my main notebook), the keyboard seemed to suit me perfectly. As with any keyboard it will take some getting used to, but I was up to my usual typing speed within a few minutes. This is always a good sign!

It should be noted, however, that there are no Caps Lock or Number Lock LEDs. This means if you’re typing in the wrong case, you’ll have to rely on what’s on screen to tell you. It’s not ideal.

Keyboard and trackpad

This isn’t to say there aren’t any LEDs on the keyboard, however. The Wi-Fi indicator, battery charging light, and the main power LED are found in the upper right.

The trackpad, meanwhile, isn’t as slick as some others (there’s no glass, for example), but it feels robust and clicks well. The trackpad and PureOS support various gestures, such as tapping two fingers to display the (right-click) context menu or dragging two fingers up and down to scroll.

A notebook computer can live or die based on the quality of the keyboard and touchpad. The Librem 13 passes with an above adequate touchpad and surprisingly comfortable keyboard.

What’s Inside the Librem 13?

Inside the anodized black shell you’ll find a powerful collection of hardware. The Skylake Intel Core i7 6500U processor is accompanied by 4GB of DDR4 RAM, with 120GB of storage. There’s the option of fast M.2 storage too, up to 2TB. M.2 is an SSD form factor that connects directly to the motherboard and offers enhanced storage speeds.

Graphics comes courtesy of the Intel HD Graphics 520, displayed on the surprisingly good 13.3-inch IPS display, with an anti-reflective matte finish.

HDMI and card reader on Librem 13

You’ll also find the usual connectivity options. Along with wireless networking, the Librem 13 has two USB 3.0 ports, a USB Type-C port, headphone port, standard HDMI-out (with 4K support), and an MMC/SD card reader.

On the left side you’ll find the radio and multimedia kill switches.

Librem 13 Linux Software and Updates

Using PureOS is straightforward. You’ll see the GNOME desktop when you log in, which is almost ubiquitous across Linux these days. A rectangle “super” key is labeled with a white rectangle, matching the Purism logo. It opens the overview, where open apps, the search box, dock, and additional desktops can all be accessed.

New apps can be found via the Software tool, which lists applications, utilities, and games that can be run on PureOS. Installing software is easy: simply search, select, and click Install. It’s also possible to install software via the command line, as usual with Linux.

Built in software includes LibreOffice, ToDo, Kodi, a Document Viewer compatible with PDF, and PureBrowser. Rather than something new, it’s basically Mozilla Firefox with the HTTPS Everywhere and uBlock Origin extensions preinstalled.

It’s worth noting some sites won’t work by default in this browser. YouTube, for instance, won’t play videos without disabling uBlock Origin.

Battery Life: Can You Stay Secure on the Move?

Purism’s website states the Librem 13 offers “roughly 7 to 9 hours” battery life.

Our review device was used regularly over a week, mainly for web browsing and word processing on the move. I’d say the battery life is in the stated area, perhaps a little less. It’s certainly good enough to not worry about three-hour trips to your favorite cafe without the mains adapter.

While it might need to chug along for intensive tasks, overall the Librem 13 is ideal for “road warrior” use.

Meanwhile, full disk encryption means that if the laptop is stolen while you’re out, no one can access your data.

Do You Need a Librem 13?

It’s ultra-secure and ultraportable, lightweight, powerful, easy to use. Sure, there are a few grumbles if you want to use closed source software, but overall the Librem 13 is one of the sexiest laptops available.

Sexy AND running Linux? No, really.

Librem 13 laptop

With a reliable, comfortable keyboard, stunning IPS display, responsive trackpad, a range of storage options and a frankly impressive battery, this is probably the best laptop I’ve ever used. It’s not a desktop replacement, it’s not a gaming laptop, but it is powerful enough to sit alongside a Dell XPS or MacBook Air and look like the best option.

Now, the security options might not be for you. You might like the look of the Librem 13 but not fancy Pure OS. That’s fine, as it can be replaced, although you’ll lose TPM support, and the kill switches won’t necessarily work.

From my point of view as a laptop user, Linux fan, and security writer, this is a superb machine that does pretty much everything I need, wherever I am.

When it comes to laptops, you can’t ask for more than that.

    My rant is about the street confusion of the contest.. shared with my brother and the link implying assured credit for his entries/participation in said contest dumps him to an unending page of articles with no visible path to the contest at all?!

      Apologies Hacim, looks like I left a stray "m" on the end of the contest URL, so he would have ended up on the 404 page. Should be working now!

    It's awfully hard to swallow those specs for the price. That's an XPS 13 with an i7-8565U, 256gb m.2 NVME and 8GB ram. As far as I can tell, the only thing the Librem offers is very expensive free software. Is there a compelling reason not to repurpose a windows ultrabook?

      Dta, The Librem 13/15 laptops are the only ones on the market (aside from some low-spec Chromebooks) that are sold with Coreboot (a free/open source replacement for BIOS/UEFI) and is fused to allow the user to change BIOS. The Librem 13/15 also disables and removes 92% of the code for the Intel Management Engine (ME), which can be used to remotely control your computer. The Librem 13/15 come with a TPM chip to prevent tampering, whereas the XPS doesn't (although you can get that with a Thinkpad X/T/W, HP EliteBook, Dell Latitude or Dell mobile Precision). If you are serious about security, the Librem 13/15 is much better than an XPS. PureOS on the Librem 13/15 is 100% free software, whereas you need binary blobs in the Linux kernel to run the XPS.

      If you are serious about software freedom or security, the Librem 13/15 is much better than a Dell XPS, but you are paying extra for the small-scale hardware manufacturing and software development that Purism does in maintaining its own Linux distro. In part, you are helping to finance a company that sees itself as fighting for user digital rights and trying to push change up the supply chain.

      "Atheros 802.11n dual antenna (no wireless option is available)"
      This needs to be changed to say that "(no Bluetooth is available without installing a proprietary driver)". The Atheros 802.11n works with a free driver, but its range is limited. People who need better range generally buy a replacement Wi-Fi M.2 card.

    It also uses systemd, a gigantic glob of I-can-do-it-all-in-one-better-than-many-'separate-made-specifically-for-each-thing' PoS, made by an egomaniac who listens to...himself.

    Prism claims on their website that the "kill switches" are hardware switches that disconnect the power to the devices. But you state that the switches may not work in other OS's? Are you speculating, or guessing or stating?

    Also I use ublock origin in Deepin Linux on Chrome and YouTube works perfect (and without any ads, video or text). Is this a Firefox ublock issue (been a while since I used Firefox).

    Finally, a month ago I downloaded PureOS from their website (when I first heard about Purism) and the OS hasn't seemed to be updated in forever (in Linux terms) and pure browser was in fact Firefox without anything different (no ublock or HTTPS everywhere installed or anything). Very unpolished and "abandoned" feeling for a Linux distribution, I found that extremely disheartening.

    If I have one complaint about Linux it is battery life on laptops. If someone can make a true 7-9 hr battery life that is not as large as a car battery I will be ecstatic. Time and use will tell..
