Best Home Security Doors of 2021

Smart locks aren't the only way to beef up a door's security—sometimes you need to start with the front door itself. The Main Door Mahogany prehung front door combines strength and style to protect your home's main entrance. Its weight makes installation tricky but hanging it is pretty straightforward. (But the weight is a good thing in the long run.)

It doesn't give you the visibility of the storm-door-style security doors, but the speakeasy portal allows for some airflow and protects you while you're chatting with someone standing on your front porch.

This wooden door features a speakeasy hatch in place of a peephole and a distressed finish with iron accents, but we found the distressing to be less aged-over-time and more attacked-with-a-hatchet than we'd like (that is, unless you literally want to look like you're living in a castle under siege).

This entry door is simple to install, but it is solid wood, so we recommend rounding up a few friends—or a professional from Thumbtack—to help with the heavy lifting. The exterior molding is not included, and you'll need to drill the hole for the deadbolt, so plan accordingly. This door works best in a protected location—you'll void the warranty if you place it on an exterior wall without an overhang.

The Su Casa's metal screen allows for ventilation and keeps insects out, but the welded steel tube scrollwork grilles add a layer of protection to your home. We like that you can choose whether you want it to open from the left or from the right and that it has a powder-coated frame and galvanized steel screen for protection against rust and corrosion.

We recommend adding an extra layer of sealant for long-lasting wear before you install it since the one-way installation screws will make this screen door tricky to remove once it's in. (One-way screws: great for preventing crime, not so great for door replacement.) This steel door comes with a one-way driver bit to make installation a little easier.

It has tamper-proof hinges, and the mesh screen (wavy though it may be) keeps out both human intruders and insect ones. The doorknob and deadbolt aren't included in the package, so you can select your own for extra safety.

For installation, be sure you have a tool on hand that can handle one-way security screws. Although this door doesn't come in a prehung configuration, it includes a frame that you assemble before hanging.

The door's interior structure is beefed up even more at the top and bottom with Laminated Strand Lumber (LSL), an engineered wood product that's specifically manufactured for enhanced structural integrity, to ensure that all the kicking in the world won't budge your door. The double-insulated tempered glass on this door offers a lot of resistance to physical attacks. You can choose different levels of privacy protection for the glass as well.

The GlassCraft ThermaPlus is a solid choice for home security, but it comes at a price—it's nearly $2,000, and getting it prehung will add another $1,000. On the plus side, it comes in six different finishes, so you can choose the color that best suits your home's design.

While the other doors in our comparison work well in any exterior doorway, this door is a better fit for workshops and garages. The biggest highlight is probably the 9–12 point locking system that secures the door on all four sides instead of focusing on the side with the handle like normal doors. It also comes with a mortise lock handle, which means you don't need to buy a door lock separately.

We love that it comes in five different sizes and includes a frame for easy mounting. The door isn't solid steel—that would be a nightmare to lift—but its hollow core contains fiberglass and mineral wool for extra insulation against heat and cold.

The Main Door Mahogany is secure and stylish. The overall look and construction of the door says, "Keep walking," which is why we named it our top pick for the best security doors.

While an exterior security door is a good start to a more secure home, if you want to take it a step further, consider other ways to strengthen door security, like installing sensors on your doors and windows and using door jammers.

For the most effective electronic door and window safety, it's important to understand how door sensors work and how to find the best door and window sensors. For no-tools-required door security, and more peace of mind when you're traveling, check out our picks for the best door jammers.

After becoming a victim of a home invasion myself, I learned that my front door was definitely my home's Achilles heel. As it turns out, my experience was no exception, and burglars often prefer breaking in through a door instead of a window.
