DATA Sanitization

your data is safe

At WALTER,  data security is our constant and foremost concern.We know that unauthorized access to sensitive information can harm an organization’s reputation and financial stability. Proper data destruction reduces the risk of data breaches by ensuring that no residual data is left behind that could be exploited maliciously. We take pride in using processes that guarantee our customers a secure and responsible destruction of their data and have never had any type of data breach.

End-to-end chain

Our data sanitization processes protect sensitive information and maintain privacy by ensuring that we maintain full chain of custody of data bearing equipment, that data is properly sanitized or physically destroyed and that any destroyed hard drives are sent onto R2 V3 certified partners for recycling

I couldn’t be happier with my experience with Walter! I run a production company and had to recycle over 75 hard drives, a few small servers, and a few broken computer towers. I was looking at upwards of $1000 for proper e-waste recycling, but fortunately I found Walter. Not only, was I able to do a same day drop off at no cost, but. . . everyone who worked there was incredibly polite and engaged, they stayed open for me (I arrived a few minutes after they normally close) and they gave me a tour of their facilities. Not only did I save my business a lot of money, I was able to do so with a place that is making a meaningful impact in their community. I’ve got this place saved on my google map cause I’ll definitely be heading back there if I need to do more e-waste recycling!

I needed a CRT tv for a school project and was incredibly fortunate to find these guys. All the TVs were already tested too so I knew what I was getting. Plenty of other older working tech available as well. Shout out to Jonathan and the team— they were all incredibly helpful. Definitely recommend.

My computer which I use both for personal and work purposes went kaput suddenly. I couldn’t spend a lot of money on a brand new computer and a friend told me about WALTER and the refurbished computers they sell. I contacted them and within days they had a fairly recent MAC all lined up for me. The staff were easy to deal with, the MAC arrived quickly and in good shape. An IT guy helping me to learn this machine marveled at how fast it was working. I paid about a third of what a new one would cost. Thank you WALTER people

I had an awesome experience visiting Walter. I went to drop off an old computer and ended up discovering a great resource. The staff was incredibly helpful and friendly. They gave me a tour of their warehouse and I ended up leaving with a hard drive. If you’re looking for reasonably priced electronics they are a great resource.
